I just mean that normal devices (NICs, storage HBAs, USB, VGA, etc.,) usually are not at bus 0, device 0, function 0. The fact that your wifi NIC is apparently is at bus 0, device 0, function 0, is unusual, so I would investigate that. Maybe there's something wrong with your platform's PCI device enumeration. >> A complete dmesg log is always a good start. >> >> I don't see anything obviously wrong. The device address (bus 0, >> device 0, function 0) is unusual, so I'd double-check that.
