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.
