[sane-devel] sane_read: Invalid argument on Epson Perfection 1640SU

[Henrik Lundberg]

Hello,
I am trying to get an Epson Perfection 1640SU to work under Debian Etch.
I'm using udev and the device file shows up as it should, and the epson
and epkowa backends detects the scanner:

$ scanimage -L
device `epson:libusb:002:002' is a Epson Perfection1640 flatbed scanner
device `epkowa:libusb:002:002' is a Epson Perfection 1640 flatbed
scanner

However, when trying a default scan it fails:

$ SANE_DEBUG_EPSON=128 scanimage -d epson 2> testscan.err
P4
# SANE data follows
424 585

testscan.err is attached.
In the error output i see a couple of lines reading '[epson] option:
fatal error'.

Packages libsane and sane-utils are of version 1.0.18-3 and scanimage -V
reports 1.0.18 as well.

I hope that you may have an idea of what's wrong.

Thank you,
/Henrik
