Dear sir/madam,
my Acer szw3300u scanner can't work under Debian 5.03 x86-64-bit,the error
as following:
open device faile:'v4l:/dev/video0' invalid parameters (szw3300u.png)
the sane-find-scanner result as following:

debian:/home/nixon# 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
  # 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=0x04a5 [Color], product=0x20de [ FlatbedScanner

  # 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.
debian:/home/nixon# scanimage -L
