   3 Subject: make raw USB printer devices accessible for lp
   4 X-Git-Url: http://git.kernel.org/?p=linux%2Fhotplug%2Fudev.git;a=commitdiff_plain;h=f61e72d8973cf9d889a4f1233150870085c0b3e1

   6 make raw USB printer devices accessible for lp
   7
   8 Starting from version 1.4, cups now uses libusb and printer USB devices instead
   9 of the usblp generated /dev/usb/lpX ones. In order to not require the cups USB
  10 backend to run as root now, change raw USB printer devices to be root:lp 0660,
  11 similar to usblpX devices.
  12
  13 This might also enable the hplip backend to not run as root, since this has
  14 always used raw device nodes.
