[wish] support for Epson Stylus DX-4050 scanner

[Laurent Riffard]

Distribution: Ubuntu 7.10

The Epson Stylus DX-4050 scanner is not detected although it is perfectltly supported by the epkowa backend.

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).

$ sudo scanimage -L
device `epkowa:libusb:001:011' is a Epson Stylus CX3900/DX4000 flatbed scanner
device `epson:libusb:001:011' is a Epson CX4000 flatbed scanner

I have to add the following 2 lines in /etc/udev/rules.d/45-libsane.rules to get it detected:
# Epson DX-4050
SYSFS{idVendor}=="04b8", SYSFS{idProduct}=="082f", MODE="664", GROUP="scanner"

I reported it to the sane-devel mailing list, it has been answered that the SANE package has just been updated (see http://lists.alioth.debian.org/pipermail/sane-devel/2007-November/020233.html).

I just installed libsane-extras 1.0.18.12, it still does not work (ie I must edit etc/udev/rules.d/45-libsane.rule to get my scanner detected).

I can confirm that this problem also occurs with the Epson Stylus Photo RX595 all-in-one.

In my case, lsusb gave:

Bus 004 Device 007: ID 04b8:083c Seiko Epson Corp.

So, the magic line in /etc/udev/rules.d/45-libsane.rules was:

# Epson RX595
SYSFS{idVendor}=="04b8", SYSFS{idProduct}=="083c", MODE="664", GROUP="scanner"

Scanning now works perfectly, though sane detects the scanner as something else

$ scanimage -L
