Mustek MFC-600S, Linux, scanimage & tkscan

TKSCAN, SANE and a Mustek MFC-600S scanner are a great combination.

Thought I would let you know about a problem I encountered using
scanimage,
tkscan and a Mustek MFC-600S. While I have sucessfully ran this setup,
initially I had several problems which required a few hours of
troubleshooting (I'm no Linux genius)

The first problem I had with scanimage is that it locks up
while doing command "scanimage -L"
I'm not certain if I need any other options, but it will lock and not
display an output. My setup consists of a INI9100 SCSI (SIIG AP-10)
controller, the
scanner on ID 03, a Multi-Lun Pioneer CD rom on ID04. I have
/dev/scanner
(a copy of /dev/sga) set to 21,0

The other problem I have is when tkscan (compiled to mustek-scanimage)
will
cause scanimage to display the output "setting option --br-y failed
(Invalid
argument)". After researching and seeing that the geometry settings put
out
by tkimage were causing this message, I checked with "scanimage --help
--device mustek:/dev/scanner" which tells me:
Geometry:
-l 0..220mm [0]
-t 0..292mm [0]
-x 0..220mm [220]
-y 0..292mm [292]
I do not know if these are max values reported by the scanner or
compiled
into the SANE Mustek driver.
However, any value set greater than these will cause the "setting option

--br-y failed (Invalid argument)" to be put out by scanimage and lockup,
and
tkscan will error out at this point as well.

In short, tkscan will put out the default geometry 0, 0, 217.222222222,
295.611111111 (for the whole sizeable scanning area) and cause problems
with
scanimage which doesn't seem to like those values.

My Mustek MFC-600S scanner has a 223mm width x 296 height maximum
scanning area,
supporting letter (8 1/2 inches x 11 inches or 216mm x 292) and A4
(210mm x
296mm). It appears that the max length value is the culprit, scanimage
(or
the scanner) only allowing an 11 inch (292mm) pagelength, and not the
max A4
(296mm) setting on my scanner glass.

Tkscan really isn't the problem, but
what I need to know in order to modify the tkscan script is if 292mm
is:
A. As far as my scanner will go (even though it has A4 page length
marks
and the glass area is 223x296)
B. Some sort of default geometry imposed by the SANE Mustek driver...
