I haven't heard of this problem before. Not sure what could be causing it. Perhaps a scsi driver problem there???

If its been a couple of weeks then you will want to grab the latest
version of CVS as of 11-27-00. That includes an update for colour
mode at higher resolutions (at least for my scanner). With my
scanner, starting around 300 dpi the scanner can lock up right
at the beginng when it calles mesasure_transfer_rate. You can
verify this yourself by setting SANE_DEBUG_SNAPSCAN to 255.
Anyways, there is a workaround for the problem in current CVS.
Hopefully, someone will have time to look into it better since
the current fix could cause invalid expected byte calcs and cause
the scanner to lock up in other places.
