F12 - no love from xsane

view story

http://forums.fedoraforum.org – I loaded up xsane and tried scanning an image.. This is the only time i've ever used xsane on fedora (new member!) anyway, i get hit with this message "Failed to start scanner: invalid argument" when i click "acquire preview" or "scan" .. i did a `strace -f scanimage -T` and it spit out a whole lot of /dev/bus/usb/blah/blah permission denied errors, so i did a `lsusb` and found the bus that my printer was plugged into. ls -l showed that it belonged to the lp group, so i added my user to the lp group; same error; did a chmod 777 on it (001/002); same e (HowTos)
