you're lucky !!!
mustek have seem to have only released one mustek driver...
and thats for the 1200ub
if you have this scanner,, and NOT the 1200ub plus (which i have)
the driver should work . (it does not work for plus)
in that tar package is a Read me, an rpm, and a src.rpm
it has instructions on how to use it as a gimp plugin...
or how to use it directly with the xscamimage command
wanna swap scanners ???
