Thanks, Uwe. I can't say that the function is obvious from the name, though!

Two files:

pi at raspberrypi ~ $ ls /etc/udev/rules.d
40-scratch.rules  99-input.rules

pi at raspberrypi ~ $ cat /etc/udev/rules.d/40-scratch.rules
ATTRS{idVendor}=="0694", ATTRS{idProduct}=="0003", SUBSYSTEMS=="usb", 
ACTION=="add", MODE="0666", GROUP="plugdev"

pi at raspberrypi ~ $ cat /etc/udev/rules.d/99-input.rules
SUBSYSTEM=="input", GROUP="input", MODE="0660"

I don't think that I needed to edit either of these files.
