Comment:
USB2:
{{{
04a9:172f /dev/bus/usb/1/0/5 "Canon, Inc." "PIXMA MP620" ver. 0109
}}}
USB3:
{{{
04a9:172f /dev/bus/usb/0/2 "Canon, Inc." "PIXMA MP620" ver. 0109
}}}
As far as I can tell, the only differences are that in the USB2 case, it
is attached to a hub; whereas in the USB3 case, it's directly attached to
the root hub. Perhaps there is some problem with the way libusb or Sanity
enumerate devices here? It's hard to say; but I doubt at this point that
it is really an XHCI issue.
CC'ing PulkoMandy; perhaps he has some ideas of what might be tried to
further diagnose the problem.
