[sane-devel] Sane no longer works

[Steve Cohen]

$ sudo sane-find-scanner
[sudo] password for scohen:

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure
that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

found USB scanner (vendor=0x138a, product=0x0017) at libusb:003:006
found USB scanner (vendor=0x04a9 [Canon], product=0x190f [CanoScan],
chip=GL848+) at libusb:003:036

OK, this is a little interesting. I only have one scanner.  What is this
first one at libusb:003:006 and why does the libusb:003:xxx for the real
scanner keep incrementing by 1 every time I run an app?
