Maybe I have misunderstood. Bjorn, can you explain the exact connection? As for disabling USB in the BIOS configuration... What that does isn't clear. It might turn off the USB hardware entirely, so that the kernel can't detect it at all. Or it might leave the hardware turned on but tell the BIOS not to use it. Do you have lspci output from an older kernel where this stuff all worked correctly?
