I need to find a gamepad in my list of /dev/input/event* devices, and the only thing I know about it is that when I do evtest it shows up with the name G13. The problem is every time I reboot it gets a different number. I would like to automate finding the path so I can pass it to this command in the $G13 variable: I tried evtest | grep G13 but the problem is the evtest command doesn't terminate on its own, it's interactive, so my script gets stuck on a prompt.

xboxdrv --evdev $G13 --config ~/.config/xboxdrv/G13.conf &

You want to set up a udev rule to provide your device with a persistent symlink. Start by running udevadm info -a /dev/input/eventXX for whichever device currently represents your gamepad.

You'll see output like:


  looking at parent device '/devices/pci0000:00/0000:00:14.0/usb1/1-4/1-4:1.0/input/input29':

Create a file /etc/udev/rules.d/90-gamepad.rules that contains:

SUBSYSTEMS=="input", ATTRS{id/product}=="c21d", ATTRS{id/vendor}=="046d", SYMLINK += "gamepad"

...replacing the values for product and vendor with the ones you see in your output.

Save the file and run:

udevadm control -R

Unplug the gamepad and plug it back in, and you should see there is now a symlink /dev/gamepad that points to the appropriate /dev/input/... device.

Now you can use the device path /dev/gamepad instead of the varying /dev/input path.

  • One year later correction: this creates a symlink to the /dev/input/jsY path, not to the /dev/input/eventXX path. Unfortunately, the command in the question cannot work with that path. I can only assume they are different protocols or something
