  Is the scanner mentioned in connection with the driver ?

  I: If#= 0 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=01 Prot=02 Driver=hid

  This is the entry for an USB mouse. In that line for your scanner the driver
  entry must be correct and not (none).

  Unused means: "currently not actively working". It would vanish only during a
  scan. This file by the way cannot be edited.

  Your problem is probably caused by autodetection not working with most USB
  scanners, unless it's a driver issue.
  Try manually setting the device file in the backend's configuration file.
