Делаю

# sane-find-scanner

  # 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.
  # Also you need support for SCSI Generic (sg) in your operating system.
  # If using Linux, try "modprobe sg".

found USB scanner (vendor=0x03f0, product=0x0705, chip=rts8801/rts8891) at 
libusb:001:004
  # Your USB scanner was (probably) detected. It may or may not be supported 
by
  # SANE. Try scanimage -L and read the backend's manpage.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

Правильно ли я понял, что сканер найден но с ним проблемы?

И дальше откуда бы не запускал пишет: Либо устройство занято, либо ошибка 
ввода вывода. Что дальше делать, куда копать, где почитать?
