[sane-devel] Epson Perfection 610 disappeared

[sedwards at xmission.com]

I've been using this Epson Perfection 610 usb scanner on this computer  
with gNewSehnse for years with no trouble (apart from some issues with  
scanning narrow documents).

Recently I have been trying out some other distros to see if some bugs  
have been fixed in more recent versions of software (including  
scanning of narrow documents).

I have been using LinuxMint 10 LXDE for a couple of weeks and one of  
the few problems I had was that when I ran scanimage I got an "Invalid  
argument".  Since I wanted to work on a Sane backend for a different  
scanner, I decided to get the latest source (1.0.22) and build a  
version myself.

That went off without a hitch and I was able to scanimage with the  
Epson with no problems.  The narrow docment problem was even fixed!

I had to reboot into a different OS (Ubuntu) and now I'm back in  
LinixMint the scanimage that I built a couple of weeks ago is no  
longer working.  It is giving me the same "Invalid Argument" message  
that I was getting with the LinuxMint package:

scanimage -depson:libusb:004:004 > xxx.pnm
[sanei_debug] Setting debug level of dll to 0.
scanimage: open of device epson:libusb:004:004 failed: Invalid argument

scanimage -L can no longer find it:

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

However sand-find-scanner CAN find it:

...

   # Your USB scanner was (probably) detected. It may or may not be  
supported by

Any suggestions as to what I should do next?
