[sane-devel] Perfection 610: cannot scan in color

[Evil Mr Henry]

Basically, "scanimage -v -d epson2:libusb:003:005 --format png > 
outfile.png" works, but "scanimage -v --mode color -d 
epson2:libusb:003:005 --format png > outfile.png" throws the classic 
"invalid argument"

(It is, in fact, an Epson Perfection 610 USB scanner.)

This is a new computer; the scanner worked on my old computer in much 
the same setup.

Running Mint (Ubuntu) 64bit, Sane 1.0.22-7ubuntu1

The following is the output after setting "export SANE_DEBUG_EPSON2=255":

scanimage -v --mode color -d epson2:libusb:003:005 --format png > 
outfile.png
