[sane-devel] Detected scanner, proper driver, won't scan

[Stan Goodman]

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.
