  # sane-find-scanner will now attempt to detect your scanner. If the

  # scanner is powered up and properly connected to your computer.

found USB scanner (vendor=0x055f, product=0x0006, chip=MA-1017?) at libusb:002:003
  # 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.

  # You may want to run this program as root to find all devices. Once you
  # found the scanner devices, be sure to adjust access permissions as
  # necessary.
[zima@pc020 MySoft]$ scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

谁能帮我看看什么问题？
