Hi all, I am using sane on hp multifunction device, i.e., HP Photosmart C4180 All-In-One. I currently use this device for printing, while I am starting using it for scanning. Every time I plug its cable, udev load the driver and set authorisations for device /dev/bus/usb/$HUB/$DEVICE. Those auths are such that root may do anything, the "lp" group may read and write, others might read.
I cannot access the device via sane, since I am not a member of lp. My Debian box include a group called "scanner" and udev assign this group to /dev/bus/usb/$HUB/$DEVICE for my other scanners (EPSON and Fujitsu). I would like to know how other people solve this problem. Are you using ACLs? May you setup ACLs directly from udev? Do you create a different group, like lpsane, and add all users of "lp" and "sane" to this group? Thanks, Giuseppe
