I do have SANE-1.0 installed. I downloaded it from the SANE
homepage just two weeks ago. I even installed the patches dated
December 98.

Ok, I see. Are there any frontends supporting 36-bit color?

There are no "shoe-shining" during scans. The head moves forward,
although it is sloooow. A scan of a CD inlay at 170 DPI (24 bit) takes about
40 seconds. According to the manual, it should scan at 6.5ms/line. An inlay is
10 inch wide and occupies 1600 lines at 170 DPI. 1600 lines at 6.5 ms/line
should result in a scan time of 10400 ms (~ 10 seconds). What am I missing?
