If you encounter any problems with getting your device(s) recognized, try
setting the various environment variables that are available to assist in
debugging such problems. The environment variables are documented in the
relevant manual pages. For example, to get the maximum amount of debug
information when testing a Mustek SCSI scanner, set environment variables
SANE_DEBUG_DLL, SANE_DEBUG_MUSTEK, and SANE_DEBUG_SANEI_SCSI to 128 and then
invoke scanimage or whatever program you're trying to debug. For a Mustek
scanner at /dev/scanner, you might want to invoke scanimage as follows:
.BR SANE_DEBUG_DLL ", " SANE_DEBUG_MUSTEK ", and " SANE_DEBUG_SANEI_SCSI
to 128 and then invoke
.B scanimage
or whatever program you're trying to debug. For a Mustek scanner at

you might want to invoke
.B scanimage
as follows:
.IP
scanimage -d mustek:/dev/scanner -h
.B scanimage \-d
.I mustek:/dev/scanner
.B \-h
.TP
If this works, you could try to acquire an image with:
.IP
scanimage -d mustek:/dev/scanner >t.pnm
.B scanimage \-d
.IR mustek:/dev/scanner " >t.pnm"
