The UC630 is a scanner that I don't know very good. The scanner does not
give back a lot of informations so I had include the missing values
into the driver, but I am not sure if all are ok.

There seem to be some problems with some firmware-versions.

Please send me a little scanned picture, if you like with some
different gamma-values.

Bye
Oliver
