Before that, of course, it is still completely unclear whether it is a software error, which would be a lot easier to fix, or whether it is not caused by the hardware itself. Most disconnections should primarily occur when high data rates are being transferred for a long period of time. The USB problems should be provoked particularly well with VR headsets, as you can read on Reddit.
The use of a PCIe 4.0 graphics card is often cited as a possible source of the problem, as is currently only possible with NVIDIA’s RTX-3000 and AMD’s Radeon RX-5000/6000 graphics cards. A workaround is to switch from PCIe 4.0 to PCIe 3.0 in the BIOS, which is the “solution” in some cases. However, there is still only a workaround instead of a real solution. Furthermore, it should be sufficient for some users to deactivate the USB power saving modes in Windows 10.
AMD is looking for a solution with those affected
On Reddit, AMD has now officially commented on the USB problem:
“AMD is aware of reports that a small number of users are experiencing intermittent USB connectivity issues reported on 500 Series chipsets. We have been analyzing the root cause and at this time, we would like to request the community’s assistance with a small selection of additional hardware configurations. Over the next few days, some r/Amd users may be contacted directly by an AMD representative (u/AMDOfficial) via Reddit’s PM system with a request for more information.
This request may include detailed hardware configurations, steps to reproduce the issue, specific logs, and other system information pertinent to verifying our development efforts. We will provide an update when we have more details to share. Customers facing issues are always encouraged to raise an Online Service Request with AMD customer support; this enables us to find correlations and compare notes across support claims.”
Accordingly, those affected by such USB problems can and should contact AMD directly and should then of course mention the hardware used and the steps with which the USB problems can be provoked. But the story with VR headsets already seems to serve as a good example of where AMD can start directly. It will also be interesting to see what the final solution will look like. In the best case, an AGESA update is sufficient, which the mainboard manufacturer then has to implement in the respective BIOS. Of course, it is also questionable how much time will pass before AMD has found the cause of the disconnections.
