Trying the suggested test from SANE via issuing "scanimage -L" does not reveal the mutual video device as described like "v4l:/dev/video0". The scanner is seen on a Linux Ubuntu box as such a device, but I had no further chance for testing, whether the scanner works on that particular system. webcamd obviously recognises the scanning device as a video device. But how can I introduce the device to SANE or even GIMP? Are there further patches for the device driver necessary?
