I configured this scanner in YaST, and can use it through USB as root. But I can't use it as a user. Thanks to the other recent thread about scanning, I did this: enterprise:/etc/sane.d #SANE_DEBUG_DLL=3 scanimage -L [sanei_debug] Setting debug level of dll to 9. [dll] sane_init: SANE dll backend version 1.0.8 from sane-backends 1.0.11 [dll] add_backend: adding backend `hp' [dll] load: searching backend `hp' in `/usr/lib/sane' [dll] load: trying to load `/usr/lib/sane/libsane-hp.so.1' [dll] load: dlopen()ing `/usr/lib/sane/libsane-hp.so.1' [dll] init: initializing backend `hp' [dll] init: backend `hp' is version 1.0.8 device `hp:libusb:001:002' is a Hewlett-Packard ScanJet 62x0C flatbed scanner [dll] sane_exit: exiting [dll] sane_exit: calling backend `hp's exit function [dll] sane_exit: finished As the user, though, I get: david@enterprise:~> SANE_DEBUG_DLL=9 scanimage -L [sanei_debug] Setting debug level of dll to 9.

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). [dll] sane_exit: exiting [dll] sane_exit: calling backend `hp's exit function [dll] sane_exit: finished The problem obviously lies in the permissions, but I have no idea what permissions to set on the device "hp:libusb:001:002" so that a normal user can operate the scanner. I tried using `lsof' while scanning as root, but I don't even seen any devices in the list. (I don't know much about lsof, so I may not be using the right flags.) Can anyone tell me how to setup a "libusb" scanner for regular users? Thanks, dk
