AMD Acknowledges USB Connectivity Issues on 500 Series Chipset Motherboards
Users have recently been reporting various intermittent USB connectivity errors on AMD 500 series motherboards. AMD has acknowledged these issues in a recent Reddit post where they have asked affected users for more information to help them resolve the issues. The issues appear to be most commonly found when using VR headsets on X570 motherboards where intermittent connectivity issues are most noticeable. Some of the affected users report that the issues are most common when using a PCIe 4.0 GPU and that switching to PCIe 3.0 can sometimes resolve the issue. AMD is asking affected users to submit reports through their Online Service Request platform and will also contact users directly on Reddit to request detailed information.
Update Mar 9th:
AMD has provided some official guidance for affected users asking them to follow the solutions provided by Reddit such as disabling global C-States and switching to PCIe 3.0 mode if general troubleshooting has failed. AMD has reaffirmed that they were aware of the issue and that their engineers are actively working on a fix.

I had usb issues with not being able to jailbreak an ipad using a checkra1n on linux (debian, arch, odysseyn1x which i think is based on void?) all of which has the same problem with not being able to jailbreak the ipad failing at usb errors while my intel based machine from 2013 does it perfectly without issues.
Another thing, I tried restoring a bricked android device (Red Magic 3 Ubrick tool by Nubia) It never worked once on my amd based system, I even fresh installed windows just to make sure it wasn't on my end but nope it wouldn't work. at that time I simply went to a shop which fixed it using the same tool.
the android device unbrick was before I even knew about the USB issues the ipad one was after i knew about the existance of them but never really paid attention, it just so happens that on a whim I thought maybe I was being affected by the usb issues so maybe I should try jailbreaking on an intel machine which worked immediately and heck I even rejailbroke multiple times and it always worked then I rejailbroke again using the amd system and an immediate fail.
unbrick tool was windows only jailbreaking on linux only.
But then again, im only using PCI-E3 GPU and m.2 nvme, and some say that its the PCIE4 that is causing the issue?
edited : I'm running PCIe Gen 4.0 for my RX5700XT, all tweak from 1usmus1 like Ryzen Power Plan (enabling C-States in BIOS) and Ryzen Memory Calculator. Try with USB 2.0, I had much luck with it for OEM unlocking or adb tweaking rather than if I was using USB 3.0
I did not notice any problems with USB itself so far.
My Roccat mechanical keyboard is sometimes not detected on boot but that issue is not from AMD. It happen ones maybe 100 new reboots.
I had that keyboard since ages and experienced the same issue on my previous intel system.
It was happening on Intel more often than now. So I think that is not related x570 but keyboard itself.
Other than that I have lot of devices attached to USBs, printer, Gaming Headset, card reader, two mice (work and gaming separate ones) but did not notice any issues.
Gigabyte X570 + R7 3700 + RTX 3080. This issue happened on my motherboard's USB 2.0 ports. It is not only limited to happen on VR headsets, but also on any general USB peripherals: mouses, keyboard, microphone, any you can name. Once PCIe is changed from 4.0 to 3.0, the issue is gone. However it is definitely not a resolution.
Very interestingly, affected user may find that the writing speed of PCIE 4.0 M.2 slot 1 will be limited to 1000 MB/s. Slot 2 doesn't have such issue. Reportedly from Reddit, the solution is to do a formatting on the slot 1 SSD.
I haven't seen any issues with other USB devices so only storage devices cause problems in my case. I also haven't seen problems when single USB storage devices are connected.
I don't remember any issues with USB on many other X570 and B550 motherboards but I don't think I was ever using more than 2 storage devices at once on any previous motherboard (I had maybe 10-12 more in tests).
I tried this on my own Asus ROG Strix B550-A Gaming and my mouse is working better no small hitching or shuttering.
I don't remember any mouse issues while booted into Tumbleweed Linux. As far as I can tell, on 2 laptops here, it's 100% software issue.
