AMD admits there are problems with USB devices on 500-series motherboards

Since the Reddit post was made, the issues have been widely commented on by multiple users who experienced said issues. Users report that their USB connections will drop in a frequent manner, causing keyboards, recording devices, or even VR headsets to lose connection. The VR headsets are probably the easiest way to reproduce the issue, as reported by the users. A system equipped with a high-end GPU based on a PCIe Gen4 interface in addition to a VR headset (which relies on high-power USB connections), can easily lead to USB devices disconnect.
Workarounds have been suggested, such as reducing the PCI Gen4 to Gen3 or by disabling the “C-States” in BIOS. However many users have reported that those do not solve the problem, but rather reduce the frequency on which they are experienced.
The root cause of the intermittent USB connectivity issues is unknown. AMD is likely to collect more data and hopefully provide a fix in the future AGESA firmware.
