The scanner is Epson 640U, in recently installed openSuSE v11.3. YaST > Scanners finds it and identifies it correctly; I have chosen the epson2 driver.
:~> scanimage -L device `epson2:libusb:003:002' is a Epson Perfection640 flatbed scanner :~> scanimage -T scanimage: sane_start: Invalid argument Attemps to scan produce "Failed to start scanner. Invalid argument", which is not very informative. A review of a number of Google hits doesn't add more. I have reviewed the xscan preferences screens, but have had to admit defeat, and the fields are not sufficiently explained for me. I am assuming (hoping) that I have left something undone, but have not found anything to point me to it. Ideas? Please. -- Stan Goodman Qiryat Tiv'on Israel
