AMD admits 500-series chipset motherboards have problems with the USB interface
About 3 months ago, many users who bought AMD-500 series chipset motherboards posted complaints against AMD on Reddit, stating that their USB devices would be disconnected frequently. This problem occurs whether it is connected to a keyboard, microphone, or VR headset
Among them, users who are connected to VR headsets say that they are more likely to encounter problems. As long as the computer is equipped with a high-performance graphics card that supports the PCIe 4.0 protocol, and then uses a VR headset that requires a large amount of USB transmission, the connection will be crazy.
In this regard, some users have proposed a solution, which is to limit the rate of PCIe 4.0 to the PCIe 3.0 standard, or directly disable “C-States” in the BIOS. However, many users said that this method cannot solve the problem, but can only reduce the frequency of the problem.
Recently, AMD responded that
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.
