VIA USB 3.0 controller doesn't work in Linux. The AMD IOMMU is enabled in the BIOS. Checking kernel messages (dmesg
) shows that the USB controller is shut down due to an error, and there are also many error messages pertaining to AMD-Vi and access to a certain memory address through the IOMMU. Some USB ports do not work.
