AMD is investigating USB problems with 500 series chipsets
On Redit, AMD started collecting user info from end-users that experience USB issues on the 500 series motherboards. USB issues include intermittent disconnection of USB devices such as keyboards, mice or VR headsets. The company is now actively investigating the cause.
AMD reports on Reddit that the company is aware of the problem and that it is looking for additional data. Over the past weeks various Reddit discussions surfaced in which users report that the connection of multiple USB devices fails periodically. While possible fixes have been published, they don't seem to work for all users. Users can revert their PCIe connections to PCIe 3.0 or disable 'C-States' in the bios. However, several users report that this does not completely solve the problems, although the problem is said to be less common.
The company asks for help on the Reddit community. AMD now on Reddit has a statement in which they ask you (if you have the issue) to you examine the USB disconnections with the 500 chipsets in an offer so find a solution. Reddit users will be contacted to take a closer look at the respective use-cases. Users are also asked to start an online service request to report problems.
The focus on the chipsets is the 500 series however similarities have been reported on other platforms as well, current observations include that Vermeer and possibly a not fully developed power-saving function occasionally lead to issues with USB connections.
AMD mentions it will provide new details as soon as more is known about the problem and its cause. Furthermore, any user experiencing USB problems will be prompted to contact AMD Customer Service.

I had some bad USB problems on my ASUS ROG Crosshair VIII Hero (WI-FI) X570 board after updating the BIOS, but I cannot remember what the BIOS number was.
My USB audio interface, an RME Fireface UC kept dropping connection for a fraction of a second, which I'd never seen before on my previous Intel build. RME are famous for their rock solid audio drivers, so I was very surprised (and annoyed) to see this happening.
I also had issues with my Razer Deathadder USB wired mouse which would just stop working at random intervals. I could be 2 minutes into playing a game and suddenly the mouse would just stop working for no reason. The only thing that would bring it back to life was rebooting the PC.
I tried everything to solve this, re-installing drivers, software, changing devices to different USB sockets, but nothing would fix it. Finally, I updated the BIOS and that seemed to fix it. So, I definitely had issues at some point using a particular BIOS version. But I cannot remember which number it was.

\The ASUS ROG Crosshair VIII Hero is basically the same as my ASUS ROG Crosshair VIII Formula board. I had issues with Audio, turned out to be some crap the "armory crate" was downloading to do with DTS audio.

It's actually a big issue with a lot of people since PCIe 4.0 was introduced, and it seems especially so if you have everything (GPU, NVMe) PCIe 4.0 capable.

No issue there on the Asrock X570 ITX/TB, with lot of thing connected and all energy saver on.
