This appears to be a feature of newer firmware revisions. If SANE
recognizes your scanner, you should be OK, though.

That's strange. It appears as if the line-distance command does not
get issued. If you run sane-0.66, make sure that "option
linedistance-fix" is turned on (if you use the default mustek.conf,
you should be fine, but verify to be sure: it's in
/usr/local/etc/sane.d/mustek.conf).

If you have the linedistance-fix on and it still doesn't work, can you
invoke scanimage with environment variable SANE_DEBUG_MUSTEK set to
255 and send me the output you get?

Hmmh, sane-scsi(5) lists the Adaptec AHA-1505 to be working fine. I'm
not familiar with that adapter, but if it has some sort of BIOS
configuration, you may have to disable synchronous transfers, tagged
queueing, and target disconnects (as documented in sane-mustek(5)).
If you get it working, please let me know what you had to do so I can
add it to the man page.
