usb/core/devio.c: Check for printer class specific request

commit 393cbb5151ecda9f9e14e3082d048dd27a1ff9f6 upstream.

In the usb printer class specific request get_device_id the value of
wIndex is (interface << 8 | altsetting) instead of just interface.
This enables the detection of some printers with libusb.
