    USB HID: don't warn on idVendor == 0
    
    It turns out that there are broken devices out there that incorrectly
    report VID/PID as 0x000, see http://lkml.org/lkml/2007/4/27/496
    
    Therefore we should not confuse users by dumping warnings and stacktraces
    in such situation. It is not possible to add quirks for such horribly
    broken devices, but currently that's not needed.
