USB scanner device support

[Matthias Play]

Hi Predrac,

thanks for your extensive explanation.

My problem was that I did not install SANE because I thought the device 
driver needs to be existent in the kernel.

After installing SANE the scanner is functional and I can use xsane for 
image scans.

Regards
Matthias
