[sane-devel] Epson Perfection 2670 and debian sid

[Erik Svensson]

I can't get it to work at all, it's detected when running 
sane-find-scanner and scanimage -L. I have downloaded and extract the 
latest firmware from epson and edit the /etc/sane.d/snapscan.conf to 
point to it. I'm running debians standard kernel v. 2.6.18-4.
I also tried to rmmod ehci_hcd according to a tips on the list, but then 
the scanner isn't found at all.

This is the debug output:

$ export SANE_DEBUG_SNAPSCAN=128

$ scanimage -L
