Canon Lide 50 on 64bits openSUSE 11.4 not working

Upgrade to 64bits openSUSE 11.4 but my Canon Lide 50 scanner is not working.

Installed the following packages:

rpm -qa |grep sane
sane-backends-autoconfig-1.0.22-1.3.3.x86_64
sane-backends-1.0.22-1.3.3.x86_64
sane-backends-32bit-1.0.22-1.3.3.x86_64
xsane-0.998-5.1.x86_64

Following the debug from scanimage

export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_GL841=255

scanimage -d genesys
[sanei_debug] Setting debug level of genesys to 255.
[genesys] SANE Genesys backend version 1.0 build 63 from sane-backends 1.0.22

[genesys] probe_genesys_devices: start

[genesys] sane_init: exit
[genesys] sane_open: start (devicename = `’)
scanimage: open of device genesys failed: Invalid argument
[genesys] sane_exit: start
[genesys] sane_exit: exit

Any suggestion welcome apart from down grade to 32-bits.

Regards

Is there any reason you are running sane-backends-32bit with a 64bit system? Is that a specific requirement for your printer? I would uninstall sane-backends-32bit to see if that works.

On my 64bit system I have installed:
sane-backends-autoconfig-1.0.22-1.3.3.x86_64
sane-backends-1.0.22-1.3.3.x86_64
xsane-0.998-5.1.x86_64

Is your printer otherwise printing?
