Scanner not working after kernel upgrade to generic 3.5.0-27 U12.10
after kernel upgrade to generic 3.5.0-27 in Ubuntu 12.10, my scanner stopped working. Xsane could not find scanner.
After reading and checking I found that there is problem with permissions of regular user.
Check if scanner is visible to the system user@user: lsusb
then check correct bus number
ls -l /dev/bus/usb/002
sane-find-scanner gave info that ther no enough permission to access USB
when running sudo sane-find-scanner it was ok.
Install Users and groups tool sudo apt-get install gnome-system-tools
Then Run users and groups form main panel then click on Manage Groups
I have added user to grups plugdev and scanner.
Everything started working as usual.
I hope that my post will help someone
