With PC motherboard manufacturers implementing 40 Gbps USB4, one wonders what's next for the [mostly] universal connectivity standard. Turns out, it is USB4 2.0, which yields the connector 80 Gbps of data bandwidth per direction, and 60 W of power-delivery (PD). Power delivery for USB4 2.0 can be as high as 240 W (48 V, 5 A). Japanese PC peripherals maker Elecom is the first with certified cables for both 80 Gbps + 60 W PD and 80 Gbps + 240 W PD. Besides power and data, both cables support DisplayPort passthrough for up to 8K @ 60 Hz (7680 x 4320 pixels). USB-IF, the governing body of the USB standard, is expected to formally launch USB4 2.0 in December 2024. A typical USB4 2.0 host controller will require at least a PCI-Express 5.0 x4 system bus connection to reach the standard's maximum bandwidth.

ASMedia announced that its USB4 host controller chip, ASM4242, has received Thunderbolt 4 certification, following its USB-IF certification earlier this year. This marks a significant milestone for the ASM4242, toward providing a comprehensive high-speed transmission solution and an outstanding user experience. The Thunderbolt 4 certification signifies that ASM4242 meets Thunderbolt's stringent standards in signal quality, compatibility, and reliability, ensuring exceptional connection stability and compatibility.

Thunderbolt 4 is fully compatible with USB4, integrating power, data transmission, and video display into a single interface, offering up to 40 Gbps bandwidth to meet the demands of high-speed file transfer, 100 W fast charging, and multi-display setups. A single cable can daisy-chain up to 5 devices, driving high-bandwidth data, power, and video transmission. Gamers, creators, and professionals can connect multiple displays and accessories through this powerful connection standard. They can also enjoy a clean and convenient workspace.

Silkland, a tech brand specializing in cables and accessories, has once again raised the bar with its new 4ft USB-IF Certified USB4 Cable. This latest cable delivers unmatched speed and convenience, and works seamlessly with all Thunderbolt 4 / 3 / Type C devices, making it an essential tool for professionals and everyday users alike.

Silkland's latest offering stands out as the longest USB-IF certified USB4 cable, measuring at 4ft. This means users can now enjoy a longer reach without compromising speed and efficiency compared to the standard 3.3ft cables. Fully supports the latest features to future-proof your setup. Backward compatible with USB 3.2 Gen 2, USB 3.2 Gen 2 x2.

VIA Labs, Inc. (VLI), a leading supplier of USB4, USB 3.2, and USB Power Delivery Controllers, today announced that the VL832 USB4 Endpoint Device Controller achieved USB4 certification from the USB Implementor's Forum (USB-IF). VIA Lab's VL832 supports USB 40 Gbps operation and is now listed on the USB-IF Integrator's List under TID: 10033.

VIA Lab VL832's USB-IF Certification represents a key milestone in the USB4 ecosystem. The certified USB4 device controller with an integrated USB 3.2 USB 10 Gbps Hub, USB 2.0 Hub, and DisplayPort output, provides essential connectivity for peripheral devices such as multi-function adapters and docking stations. In USB4 40 Gbps mode, VL832 supports full DisplayPort HBR3 bandwidth (32.4 Gbps), and the USB 20 Gbps hub can enable multiple USB 10 Gbps devices to operate at full performance on supported host platforms. Both metrics are double what was previously possible using DisplayPort Alternate Mode, which is limited to 2-lanes of DisplayPort when supporting USB 3.2 functionality.

VIA Labs, Inc. (VLI), a leading supplier of USB4, SuperSpeed USB, and USB Power Delivery Controllers, today announced that the VL108 USB PD 3.1 and DP Alt-mode controller achieved USB-IF certification for USB Power Delivery 3.1 with support for Extended Power Range (EPR). VIA Lab's VL108 is now listed on the USB-IF Integrator's List under TID: 9064.

With the release of the USB Power Delivery 3.1 specification's EPR functionality, the maximum charging rate of USB Type-C was increased from 100 W to 240 W. Previously, the 100 W limit was sufficient for smaller laptops, but higher-powered 15" or larger models with discrete graphics cards often relied on proprietary charging schemes. As certified USB Power Delivery 3.1 silicon with support for EPR becomes available, many vendors are preparing to launch products featuring the new charging modes by the end of the year.

Regular readers of TPU might remember our in-depth USB4 article that we posted almost a year ago, but since then, very little has happened and ASMedia has as yet to make its ASM4242 USB4 host controller available to its partners and then ASM2464 USB4 to PCIe 4.0 bridge was suffering the same fate until May this year, when it was released to ASMedia's customers. It turns out most of it is related to USB-IF certification and the USB4 design documentation, as the certification wasn't quite ready for a third party host controller and the design documents were—shall we say—less than complete and relied too heavily on the Thunderbolt 3 spec. This meant that ASMedia had to retest and redo a lot of work they had done, due to a certain spec donator having assumed that other companies knew how it had designed its Thunderbolt products.

The good news is that we should see the ASM4242 in the market before the end of this year and ASMedia is busy testing it and its ASM2464 with a wide range of products to make sure compatibility is as good as possible. In the company suite at Computex, ASMedia was showing the ASM2464 connected to Apple's M2 silicon, as well as Intel's latest CPUs with integrated Thunderbolt 4 support. There had been some performance related issues from Apple's side, but this has apparently been resolved in a recent update from Apple. As far as Intel is concerned, there are no compatibility issues with the 13th and possibly 12th gen mobile chips, but older Thunderbolt hardware might require a firmware update, which may or may not exist. Older Intel hardware also doesn't perform as well as its most recent solutions, but it doesn't mean there will be compatibility issues outright. As for AMD, ASMedia informed TPU that there were no issues, since AMD has a USB4 implementation in its mobile products that follow the USB-IF spec.

Intel has demonstrated an early prototype of next-generation Thunderbolt in action, aligned to the USB Implementers Forum's (USB-IF) release of the USB4 v2 specification this week. Next-generation Thunderbolt will deliver 80 gigabits per second (Gbps) of bi-directional bandwidth and enable up to 120 Gbps for the best display experience, providing up to three times the capability of today's technologies to meet the growing needs of content creators and gamers, all while maintaining compatibility with previous versions of Thunderbolt and USB.

"Intel has always been the industry pioneer and leader for wired connectivity solutions, and Thunderbolt is now the mainstream port on mobile PCs and integrated into three generations of Intel mobile CPUs. We're very excited to lead the industry forward with the next generation of Thunderbolt built on the USB4 v2 specification, advanced to this next generation by Intel and other USB Promoter Group members," said Jason Ziller, general manager of the Client Connectivity Division at Intel.

USB Implementers Forum (USB-IF), the support organization for the advancement and adoption of USB technology, today announced the publication of the USB4 Version 2.0 specification, a major update to enable USB 80 Gbps performance over the USB Type-C cable and connector. The updated USB4 specification doubles the maximum aggregate bandwidth of USB to the benefit of higher-performance displays, storage, and USB-based hubs and docks. The USB Type-C and USB Power Delivery (USB PD) specifications have also been updated to support this higher level of data performance.

"For engineers, USB4 is defined by its multi-protocol tunneling that architecturally differentiates it from its predecessors - USB 3.2 and USB 2.0," said Brad Saunders, USB-IF Board Chair and CEO. "This updated technical specification extends USB4 speed and data protocol performance, enabling manufacturers to develop products that can deliver USB 80 Gbps in addition to existing USB 40 Gbps and USB 20 Gbps to end users."

The USB Implementers Forum (USB-IF) has announced a few changes to the various logos that are tied to the USB standard. This is said to be done to simplify the plethora of logos that are currently being used and to make it easier for consumers to know what they're buying. At the same time, the old SuperSpeed USB logo is being retired and the branding will not appear on new products at all. Instead, the logos that were developed for the USB4 standard and USB PD 3.1, will be adapted across the board. The new changes will come into effect this quarter and could appear on new products before the end of the year.

The new logos that will replace the SuperSpeed logo are pretty straightforward, with a 5 and 10 Gbps logo being added to the 20 and 40 Gbps logos that we've already seen. These logos will be used for packaging, on cable connectors and even on some devices. The new 5 and 10 Gbps logos can also be combined with the 60 W and 240 W charging logos when used with USB-C cables. All of this should make it easier as a consumer to know what kind of cable you're buying, but keep in mind that these logos only apply to certified products and not all USB cables are certified. Still, it's an improvement overall and should make life easier when shopping for cables, assuming the new logos are being used properly.

It was only yesterday that the USB Promoters Group announced the USB4 Version 2.0 spec with support for speeds of up to 80 Gbps, something TechPowerUp mentioned at the end of our USB4 article back in June. Now details of a 120 Gbps asymmetric mode has popped up, courtesy of Angstronomics and we've managed to confirm that it is indeed something that is coming from one of our own sources. We were in fact told back in June that the 80 Gbps mode was meant to be asymmetric, but this was not mentioned in the recent press release.

The 120 Gbps mode will use three of the four data pairs for upstream data and the fourth 40 Gbps data pair will be for downstream data from and to the host controller.Asymmetric data transfers are nothing new over USB Type-C cables, as the DP Alt Mode is already taking advantage of this. This is possible because USB4 Version 2.0 will move to PAM3 (Pulse-Amplitude Modulation) data encoding from today's 64/66- or 128/132-bit encoding. The next generation of Thunderbolt is also expected to use PAM3 encoding to reach the rumoured 80 Gbps speeds that were posted somewhat by mistake by an Intel executive last year.

The USB Promoter Group today announced the pending release of the USB4 Version 2.0 specification, a major update to enable up to 80 Gbps of data performance over the USB Type-C cable and connector. The USB Type-C and USB Power Delivery (USB PD) specifications will also be updated to enable this higher level of data performance. All of these specification updates are expected to be published in advance of this year's series of USB DevDays developer events planned for November.

Protocol updates are also being made to enable higher performance USB 3.2, DisplayPort and PCI Express (PCIe) data tunneling to best use the higher available bandwidth. "Once again following USB tradition, this updated USB4 specification doubles data performance to deliver higher levels of functionality to the USB Type-C ecosystem," said Brad Saunders, USB Promoter Group Chairman. "Solutions seeing the most benefit from this speed enhancement include higher-performance displays, storage, and USB-based hubs and docks."

Taiwanese ASMedia appears to become the first peripheral chipset company to launch a USB4 host-controller chipset, based on reports from an event the company held this week. ASMedia is at least the first company to get certified by the USB-IF, as its ASM4242 host-controller is the first of its kind to get certified. The ASM4242 was certified alongside the ASM2464PD device controller, although it's unclear exactly what type of device controller this is, but the PD in the model name indicates that it has native support for USB PD power delivery, without the need of any additional chips. This should allow for simpler implementation, as well as it would be saving some PCB space that the extra components no longer take up.

The ASM4242 is said to have a PCIe 4.0 x4 interface and does as such support up to 64 Gbps of bandwidth. As this is a two port controller, it's still not quite enough to enable both ports to operate at the full 40 Gbps that USB4 Gen 3x2 supports, but it should be enough for most consumer implementations. ASMedia has also added support for DP Alt Mode and USB4 is of course also backwards compatible with Thunderbolt 3. ASMedia is already sampling its partners. We should hopefully get a better look at what ASMedia is working on next week, but DigiTimes mentions that ASMedia has also developed PCIe 5.0 controllers of some kind and have finished the tape-out of said products.

Teledyne LeCroy, the worldwide leader in USB protocol test solutions has announced availability of their USB4 compliance test option for the Voyager M4x analyzer and exerciser system. This software option can be used in conjunction with the USB Implementers Forum's (USB-IF's) USB4 Command Verifier (USB4-CV) software to generate traffic conditions and verify responses for the official USB4 logical, protocol, and tunneling layer compliance test specifications.

USB4 combines the simplicity of the USB Type-C connector with scalable performance capable of delivering data, video, and power across a range of platforms. Design and test engineers that embed this technology into their products need robust compliance test tools to help ensure interoperability and reduce time to market. Introduced in 2019, the Voyager M4x test platform has filled a critical role for early developers performing testing, debug, and analysis of USB4 protocol layer behaviors, and the built-in USB4 exerciser option can emulate custom traffic conditions to ensure devices offer robust operation. Now, the USB4 compliance option enables the Voyager M4x exerciser to support the USB-IF's USB4-CV software for executing approved compliance tests while determining pass/fail results from traces captured by the analyzer.

Last week, the EU Commission announced that it's working towards making USB-C the universal standard for charging portable electronics and this week, the USB-IF is bringing new Certified USB Type-C cable and Certified USB4 logos to help consumers figure out what is what. However, the USB-IF is also pointing out that consumers should only buy Certified USB products from trusted sources, suggesting that there are a lot of products in the market that don't meet the various USB specifications.

The new logos can be seen below and the first one is for devices that support 40 Gbps speeds over USB. Keep in mind that although USB4 is broadly based on Thunderbolt 3, the cables aren't going to be exactly the same, but that some USB4 implementations can also support Thunderbolt 4, just to complicate things a little bit extra. This logo can also be used with 40 Gbps capable ports on devices.

USB Implementers Forum, the organization behind the development of the USB standard and its iterations, has today announced the latest revision to the USB-C standard. In the latest 2.1 version of the USB-C specification, we are in for a surprise when it comes to power delivery. With the previous 2.0 standard, USB-C was rated to deliver a minimum of 3 Amps at 20 Volts or carry a high-power 5 A current that is capable of delivering 100 Watts at 20 Volts. However, in the latest specification, the USB-IF has decided to bump up the power delivery target to a whopping 240 Watts.

This means that with the 2.1 specifications, the USB-C standard will be able to output as much as 48 Volts with a 5-Amp current. While this is a somewhat big change, that doesn't mean that you have to throw away your old USB-C cables. In the mode called Extended Power Range (EPR), the USB-C 2.1 will still work with all of the existing plugs. The plug is physically the same, however, for EPR to work it has changed the connector configuration a bit where pins for power delivery and USB 2.0 support can no longer short to ground, to prevent arcing when the cable is unplugged. The EPR cables will carry an electronic mark with them, so all of the devices will ask them how much power they can carry before transferring it over those cables. The 240 Watt bump will enable us to see more mobile devices, like laptops, with the ability to charge over a USB-C cable.

AMD's mysterious Nashira Summit GPU has been spotted in Ashes of the Singularity database. A similarly named Nashira Point GPU has appeared some time ago on the USB-IF website, which was also a mysterious product in AMD's Radeon graphics processors lineup. The Nashira Summit and Nashira Point seem to be a part of the common Nashira GPU family, which is presumably a codename for a lower-end Navi 22 or Navi 23 GPU models. Today, we managed to get a Nashira Summit score in the Ashes of the Singularity database. The GPU has been put through a set of AotS benchmarks and we have the scores. Unfortunately, tests have been run using all-custom settings, so it is impossible to compare it to some other GPU as a reference. The test was probably performed by AMD or some AIB. So far it is impossible to distinct whatever this is a mobile or a desktop product as both mobile and desktop GPUs are tested in the same manner. It remains a question what the mysterious Nashira Summit GPU is, so we have to wait for more information to find out.

AMD has recently submitted two new Ryzen 5000 series CPUs to the USB Implementers Forum for compliance. The first listing for a Ryzen 9 5980HX is a new SKU which we haven't seen before which would be positioned above the 5900HX, 5900H, and 5900HS. It is unclear what this processor will offer whether it be higher clocks, more cores, or something else. These new Zen 3 Cezanne Ryzen 5000H mobile processors are expected to be announced by AMD next week.

The second processor submitted by AMD is the Ryzen 7 5700G which appears to be a desktop Zen 3 Cezanne APU. The processor is likely to feature 8 cores and 16 threads, but clock speeds are GPU specifications are unknown. The current generation Ryzen 4000G series is only available to OEMs and was not released to the DIY market. This new desktop APU will be a significant step up from the quad-core Ryzen 5 3400G which is the fastest APU available from AMD in the DIY market.

Device IDs of Intel's upcoming line of standalone USB 4.0 host controllers leaked to the web, courtesy Hardware Leaks (@_rogame). The controller possibly comes in three variants, bearing device IDs 0x9A1B, 0x9A1D, and 0x9A13. The alleged Intel confidential document screengrab speaks of USB 4.0 and USB 3.2 support (no mention of USB 2.0/1.1), and USB Power Delivery 3.0.

With USB 4.0, the USB-IF (USB Implementers Forum, or the special interest group behind USB), appears to want to standardize the USB type-C connector, eventually phasing out the type-A connector. To that effect, the document leaves out mention of USB 2.0/1.1 backwards compatibility. USB 4.0 debuts with an interface bandwidth of 40 Gbps, or 8 times that of USB 3.0, or over 80 times that of USB 2.0.

USB Implementers Forum (USB-IF), the support organization for the advancement and adoption of USB technology, today announced an updated USB Device Class Definition for MIDI Devices, Version 2.0 in support of MIDI 2.0 devices. The standard represents an industry-wide effort by the USB-IF, MIDI Manufacturers Association (MMA), and Association of Musical Electronics Industry (AMEI) to provide MIDI users with an expanded MIDI environment connected by USB.

"USB-IF is proud to support the MMA and AMEI by publishing an updated USB Device Class Specification for next-generation MIDI devices," said Jeff Ravencraft, USB-IF President and COO. "USB has been an integral part of the MIDI environment over the past 20 years, and we look forward to seeing innovative new devices that are enabled by this updated specification."

The graphics cards of the near-future could see a gradual phase out of standard-size DisplayPorts in favor of USB 4, starting 2021, according to a CNET report. Within the USB standard, the type-C port could see a significant growth in proliferation, and a possible phase-out of type-A ports, beginning with notebooks. The USB Implementers Forum (USB-IF), had in Q3-2019 announced the USB 4.0 specification, with development of the first implementations of the standard underway.

According to the CNET report, some time in 2021, USB 4.0 type-C ports could include DisplayPort 2.0 wiring, enabling 8K and 16K displays with a single cable. USB 4.0 will also make significant strides in other directions, such as support for 40 Gbps bandwidth (80 Gbps in x2 mode). It also implements tunneling technology carried over from the Thunderbolt specification, allowing you to daisy-chain devices (such as plugging in an external hard drive to a USB 4 monitor).

The Video Electronics Standards Association (VESA ) today announced that it has released version 2.0 of the DisplayPort Alternate Mode ("Alt Mode") standard. DisplayPort Alt Mode 2.0 provides seamless interoperability with the new USB4 specification published by the USB Implementers Forum (USB-IF), and fully enables all of the features in the latest version of the DisplayPort standard (version 2.0) through the USB Type-C (USB-C) connector. With DisplayPort Alt Mode, the USB-C connector can transmit up to 80 Gigabits per second (Gbps) of DisplayPort video data utilizing all four high-speed lanes in the cable, or up to 40 Gbps with simultaneous SuperSpeed USB data delivery. VESA anticipates first products incorporating DisplayPort Alt Mode 2.0 to appear on the market in 2021.

DisplayPort 2.0, which was introduced in June 2019, provides up to a 3X increase in data bandwidth performance compared to the previous version of DisplayPort, as well as new capabilities to address future performance requirements of displays. These include beyond-8K resolutions, higher refresh rates and high dynamic range (HDR) support at higher resolutions, improved support for multiple display configurations, as well as improved user experience with augmented/virtual (AR/VR) displays, including support for 4K-and-beyond VR resolutions. Featuring the highly efficient 128b/132b channel coding shared with USB4, DisplayPort 2.0 delivers a maximum payload of 77.37 Gbps across four lanes (up to 19.34 Gbps per lane)—supporting ultra-high display performance configurations such as an 8K (7680x4320) display with 60 Hz refresh rate with full-color 30 bpp 4:4:4 HDR resolution uncompressed, and 16K (15360x8460) 60 Hz display with 30 bpp 4:4:4 HDR resolution with compression. With the release of DisplayPort Alt Mode 2.0, all of these high-performance video capabilities are now available to the USB ecosystem.

USB Implementers Forum (USB-IF), the support organization for the advancement and adoption of USB technology, today announced the publication of the USB4 specification, a major update to deliver the next-generation USB architecture that complements and builds upon the existing USB 3.2 and USB 2.0 architectures. The USB4 architecture is based on the Thunderbolt protocol specification recently contributed by Intel Corporation to the USB Promoter Group. It doubles the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols.

The development of the USB4 specification was first announced in March 2019 by the USB Promoter Group. It is now officially published by USB-IF and available for download here.

You would have thought that the USB Implementers Forum (USB-IF) would have learned their lesson the first time around with the rebranding of USB standards; however, that doesn't seem to be the case. At MWC 2019, they announced that the USB 3.2 standard would include the previous USB 3.0 and 3.1 specifications, but with a twist. USB 3.0, which has a data rate of 5Gbps, had already been rebranded as USB 3.1 Gen 1, will now once again be rebranded as USB 3.2 Gen 1. Meanwhile, USB 3.1 Gen 2 with a data rate of 10Gbps will be renamed USB 3.2 Gen 2. Finally, the new kid on the block which has a data rate of 20Gbps will be officially named USB 3.2 Gen 2x2.

While there is a reason for these names, the fact remains that it doesn't do consumers any favors. USB 3.2 Gen 2x2 gets its name from the two high-speed 10Gbps channels it uses to achieve the new data rate. Keep in mind that previous USB standards only allowed for one channel, and only USB Type-C connectors allow for dual channels. This, as you may have guessed by now, means USB 3.2 Gen 2x2 is only usable via USB Type-C connectors. To try and reduce confusion, USB-IF has suggested that vendors use marketing terms on top of the current naming scheme to help consumers understand what is what in the world of USB. <s>USB 3.0</s> <s>USB 3.1 Gen 1</s> USB 3.2 Gen 1 will be marketed as SuperSpeed USB, and USB 3.2 Gen 2 will be marketed as SuperSpeed USB 10Gbps as per our sources. Finally, the newest standard will use SuperSpeed USB 20Gbps as its marketing term, not that it will do much if implementation of the new standard will take as long as it took for USB 3.2 Gen 2 and the Type-C connector.

USB Implementers Forum (USB-IF), the support organization for the advancement and adoption of USB technology, today announced the launch of its USB Type-C Authentication Program, marking an important milestone for the optional USB security protocol. The USB Type-C Authentication specification defines cryptographic-based authentication for USB Type-C chargers and devices.

USB Type-C Authentication empowers host systems to protect against non-compliant USB chargers and to mitigate risks from malicious firmware/hardware in USB devices attempting to exploit a USB connection. Using this protocol, host systems can confirm the authenticity of a USB device, USB cable or USB charger, including such product aspects as the capabilities and certification status. All of this happens right at the moment a connection is made - before inappropriate power or data can be transferred.

"USB-IF is excited to launch the USB Type-C Authentication Program, providing OEMs with the flexibility to implement a security framework that best fits their specific product requirements," said USB-IF President and COO Jeff Ravencraft. "As the USB Type-C ecosystem continues to grow, companies can further provide the security that consumers have come to expect from certified USB devices."

USB Implementers Forum (USB-IF), the support organization for the advancement and adoption of USB technology, today announced a USB HID (Human Interface Device) standard for braille displays, representing a collaborative step toward greater technological accessibility for people who are blind or have low vision. The standard will make it easier to use a braille display across operating systems and different types of hardware. It will also simplify development, removing the need for braille devices to have custom software and drivers created for a particular operating system or screen reader.

"This is another great example of how USB-IF device class specifications can improve people's lives," said USB-IF President and COO Jeff Ravencraft. "With more than 1,000 members worldwide, USB-IF brings companies together to improve access to technology and provide a seamless user experience."

"We see the opportunity that advancements in technology can create for people with disabilities and have a responsibility as an industry to develop new ways of empowering everyone to achieve more," said Jeff Petty, Windows accessibility program manager lead at Microsoft. "Developing a HID standard for braille displays is one example of how we can work together, across the industry, to advance technology in a way that benefits society and ultimately improve the unemployment rate for people with disabilities."
