Subject: Udev rule $attr substitution
Date: Tue, 21 Dec 2010 18:47:27 +0000 [thread overview]
Message-ID: <4D10F63F.9030005@draisberghof.de> (raw)
Hi, everyone!
I'm scratching my head over this:
Rule line:
KERNEL="ttyUSB*" RUN+="myprog %p %s{idVendor} %s{idProduct}"
%p expands to something like:
/devices/pci0000:00/0000:00:1d.7/usb1/1-5/1-5:1.2/ttyUSB2/tty/ttyUSB2
But the %s (or $attr) format string will not be substituted with anything when
using udev version 157. The same rule works fine with version 125.
When doing the attribute walk with "udevadm info", the attributes are of course
found in the parent chain.
Did I miss something?
