I still experience this problem with a Brother HL-1430 printer. However, I noticed that the device (usblp0) is assigned to the plugdev group.
The file /etc/udev/rules.d/40-permissions.rules is okay for me (line 37): SUBSYSTEM=="usb", KERNEL=="lp[0-9]*", GROUP="lp" I tried to reload the udev rules using udevcontrol, but the group didn't change to "lp". Any ideas? This is udev's log: ------- UDEV [1171105773.643218] add@/class/usb/lp0 UDEV_LOG=3 ACTION=add DEVPATH=/class/usb/lp0 SUBSYSTEM=usb SEQNUM=2413 PHYSDEVPATH=/devices/pci0001:00/0001:00:02.0/0001:01:0b.1/usb2/2-1/2-1:1.0 PHYSDEVBUS=usb PHYSDEVDRIVER=usblp MAJOR=180 MINOR=0 UDEVD_EVENT=1 DEVNAME=/dev/usblp0 ------- As reported above, [EMAIL PROTECTED]:/etc/udev# chgrp lp /dev/usblp0 [EMAIL PROTECTED]:/etc/udev# /etc/init.d/cupsys restart fixes the problem until next reboot. -- usb printer not detected to add printer https://launchpad.net/bugs/77464 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
