[gentoo-user] udev usb printer permissions

[Alexander Puchmayr]

Hi there!

Can anyone please tell me why /dev/usb/lp0 has the following onwer/group and 
permissions?

zeus ~ # ls -l /dev/usb/
total 0
crw-rw---- 1 root plugdev 180, 0 Feb  8  2007 lp0


/etc/udev/rules.d/50-udev.rules says:

[...]
# usb devices
KERNEL=="hiddev*",              NAME="usb/%k"
KERNEL=="auer*",                NAME="usb/%k"
KERNEL=="legousbtower*",        NAME="usb/%k", GROUP="usb"
KERNEL=="dabusb*",              NAME="usb/%k"
BUS=="usb", KERNEL=="lp[0-9]*", NAME="usb/%k", GROUP="lp"
[...]

I would expect /dev/usb/lp0 to belong to group "lp", so which other config 
file tells udev to put it under these onwer/group and permissions?

Thanks in advance

Something fishy somewhere.  Here is mine:

Not sure why but I don't think I have changed anything.  Maybe one of
your rules was changed or not updated somehow.
