Can you tell us more about this problem so we can fix it? Or was it a
local installation problem?

There is a README.solaris in th sane-backends tar.gz file. I have
never used SCSI on a Solaris system or a Microtek scanner but I will
try to answer anyway:

As far as I know c=controller, t=target (SCSI id) and d=LUN so
"c6t6d0" looks only a bit suspicious because it's your 6th SCSI
controller. But if it's a big machine...

Did you enter /dev/scsi/scanner/c6t6d0 into microtek.conf? I don't
know if this is necessary, however.

Try setting the environment variable SANE_DEBUG_MICROTEK to 255 for
more details (on stderr).

That's ok. If you specify the filename on the command line, both the
tests for SCSI and USB will be positive because sane-find-scanner
can't really detect the pesence of an USB scanner.

Look at the debug output, maybe you get a hint.
