Bug Description

Binary package hint: udev

Certain uses of HID devices require access to the /dev/input/event[0-9]* nodes. (My particular application happens to be using Pd to read a joystick; other applications include reading data from an arduino controller, etc.) Right now, such programs have to be run as root. If the group on the event files were something other than root, ordinary users could run such programs without jumping through as many hoops. The audio group might be a good choice for this, but plugdev would work too.

To be concrete, I am proposing to add the following line to /etc/udev/rules.d/40-permissions.rules :
KERNEL=="/dev/input/event[0-9]", GROUP="audio"

Audio devices aren't generally input devices.

Note that this scheme is generally deprecated, software should be split to use DeviceKit and obtain authority to access the device through PolicyKit
