For dapper:
Fresh install of Dapper. Connect Epson CX5400 to machine, boot machine. Start Xsane Image Scanner. Hit scan, works.

For Edgy:
Install Edgy. Boot with CX5400 connected. Start Xsane. No device detected.

For Edgy:
root@edgy:/home/nick# scanimage -L

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).

Temporary fix:
Grab dapper libsane from:
http://www.mirror.ac.uk/mirror/archive.ubuntu.com/ubuntu/pool/main/s/sane-backends/libsane_1.0.17-1ubuntu4_i386.deb
then as root
dpkg -i sane-backends/libsane_1.0.17-1ubuntu4_i386.deb

Then to prevent the package changing, do
aptitude hold libsane

[drafil (dragosfilipescu)]

I have exactly the same problem. My scanner works perfectly in Dapper, but it is not detected in Edgy. Same problem under Debian testing...

[DualCortex (main-spam)]

I have same problem. Hope this is fixed, I'm using the temporary fix and obviously because of this every time I log on to Ubuntu, I'm told there is an update for libsane.

Hello,

I'm having the same problem with my Epson Perfection 2400. sane-find-scanner finds the scanner, permissions are correct (the same problem occurs as root) but 'scanimage -L' does not find anything, although with SANE_DEBUG_EPSON=256 set, I get

[epson] attach_one_usb()
[epson] SANE Epson Backend v0.2.45 - 2000-01-09
[epson] attach(, 3)
[epson] attach: opening
[epson] attach_one_usb(libusb:003:004)
[epson] SANE Epson Backend v0.2.45 - 2000-01-09
[epson] attach(libusb:003:004, 3)
[epson] attach: opening libusb:003:004
[epson] Found valid EPSON scanner: 0x4b8/0x11b (vendorID/productID)
...
[epson] scanner model: GT-9300

and with libsane-extras installed, I get

[epkowa] SANE EPKOWA Backend 1.16.0-3 - 2005-06-29
[epkowa] attach(libusb:003:004, 3)

[epkowa] Found valid EPSON scanner: 0x4b8/0x11b (vendorID/productID)
...
[epkowa] scanner model: Perfection 2400

but in both cases I get no "non-debug" output, and xsane does not find any scanners (just exits again after searching).

The above workaround does not help either. My scanner worked fine with Dapper, though.

[Nick_Hill (nick-nickhill)]

Just checked against Feisty hurd 2. Problem persists exactly as for Edgy.

[drafil (dragosfilipescu)]

Same problem. Scanner doesn't work in Feisty, but works well in Dapper and Debian Etch.
To fix the problem I had to install libsane_1.0.17-1ubuntu4_i386.deb as Nick_Hill said on 2006-10-23.

[scottmb (scottmb)]

Is this similar to this other issue "Bug #85488 in sane-backends (Ubuntu)" ?

[Nick_Hill (nick-nickhill)]

I can confirm testing Epson scanner with Gutsy Gibbon Tribe 2 7.10 beta functions as well as on Dapper.

[mlaverdiere (mlaverdiere)]

Things are working fine for me now with Kubuntu Gutsy, with libsane 1.0.19-cvs20070505-3ubuntu2 (from official Ubuntu repositories).
