I am using the new pre-compiled software from
<http://www.ellert.se/twain-sane/> from 2/15 and I am have problems
with the Plustek back-end with the Canoscan 1220u scanner with Mac OS
10.3.2.
The scan appears to complete, but then the scanimage command appears to
hang.
Here's some basic information that everyone seems to supply.
[blah:~] blah% sane-find-scanner
# No SCSI scanners found. If you expected something different, make
sure that
# you have loaded a SCSI driver for your SCSI adapter.
found USB scanner (vendor=0x04a9 [Canon], product=0x2207 [CanoScan],
chip=LM9832/3) at libusb:002:002-04a9-2207-00-00
# Your USB scanner was (probably) detected. It may or may not be
supported by
# SANE. Try scanimage -L and read the backend's manpage.
# 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.
[blah:~] blah% scanimage -L
device `plustek:libusb:002:002-04a9-2207-00-00' is a Canon N1220U USB
flatbed scanner
I then enable debug messages.
export SANE_DEBUG_PLUSTEK=255
export SANE_DEBUG_SANEI_USB=255
and
[blah:~] blah% scanimage -T
appears to complete successfully, but
[blah:~] blah% scanimage >test.pnm
hangs the terminal window, not ever giving me back a command prompt.
The debugging information is extensive and too much to provided
completely here, but here are the last few lines.
