Plugging in a USB keyboard worked for a minute or two, and then I get exact= ly the same errors from [+0,229229] to [+0,000004] above. Same USB controller chipset as OP by the looks of things. I've managed to l= ist the Capabilities in case that's any help: 03:00.0 USB controller: VIA Technologies, Inc.
