Hello, I have an UMAX Astra 2100S with USB Interface running on my Linux Mandrake 9.2. Since the very first version of sane, I got the following problem: It scans the preview in color and everything, but hangs, when I try a real scan in grey or color. Only line mode works. Anyone has any hints for me? At the moment I am using 0.91, which recognizes my Astra as 2200. Thanks to everyone, Sinepp
