My debug messages claim that "xHCI > doesn't need link TRB QUIRK" so I'm wondering if adding my asmedia device > to the quirks list really doesn't change anything unless it's xhci 0.95. I think the intention was that the quirk would be applied for your hardware even though it claims to be version 0.96. That was gust a hopeful guess that the same change would help. > Does lspci provide that information? I'm not seeing anything obvious. I've only seen it in the diagnostic prints (that aren't normally output).
