I have uploaded this to .

According to the scanner attributes the difference between the V300
and the ScanMaker 330 is that the V300 has a 256 bytes gamma table, whereas
the the 330 has 1024 bytes gamma table. This means that the V300 works
internally with 8 bit per colour and the 330 with 10 bit.

The backend should handle both sizes, so I would have expected, that
it works with the above version, but it returned an IO-error.
If this happens for you, too, please send me a trace with the environment
variable SANE_DEBUG_MICROTEK2 set to 30.

Just be sure, that find-scanner finds the scanner before calling scanimage
or xscanimage.
