Updated Xpad Linux Kernel Driver

Driver for the Xbox/ Xbox 360/ Xbox 360 Wireless/ Xbox One Controllers

This driver includes the latest changes in the upstream linux kernel and additionally carries the following staging changes:

  • support for more compatible devices
  • support for xbox360 class controllers, that need initialisation
  • support for xbox one elite paddles
  • xpad360w: power-off by long-pressing the power button

Xbox One Controllers

This driver is only used if you connect the controller via USB.

Connecting via Bluetooth
If you get past the pairing issues, the controller will operate in the generic-HID bluetooth profile.
The xpad driver will not be used.

Connecting via XBox One Wireless Adapter (WiFi)
The adapter needs daemon in userspace, see: medusalix/xow
Opinion: rather get a controller that supports bluetooth.

Installing

sudo git clone https://github.com/paroj/xpad.git /usr/src/xpad-0.4
sudo dkms install -m xpad -v 0.4

Updating

cd /usr/src/xpad-0.4
sudo git fetch
sudo git checkout origin/master
sudo dkms remove -m xpad -v 0.4 --all
sudo dkms install -m xpad -v 0.4

Removing

sudo dkms remove -m xpad -v 0.4 --all
sudo rm -rf /usr/src/xpad-0.4

Usage

This driver creates three devices for each attached gamepad

  1. /dev/input/jsN
    • example jstest /dev/input/js0
  2. /sys/class/leds/xpadN/brightness
    • example echo COMMAND > /sys/class/leds/xpad0/brightness where COMMAND is one of
      • 0: off
      • 1: all blink, then previous setting
      • 2: 1/top-left blink, then on
      • 3: 2/top-right blink, then on
      • 4: 3/bottom-left blink, then on
      • 5: 4/bottom-right blink, then on
      • 6: 1/top-left on
      • 7: 2/top-right on
      • 8: 3/bottom-left on
      • 9: 4/bottom-right on
      • 10: rotate
      • 11: blink, based on previous setting
      • 12: slow blink, based on previous setting
      • 13: rotate with two lights
      • 14: persistent slow all blink
      • 15: blink once, then previous setting
  3. the generic event device
    • example fftest /dev/input/by-id/usb-*360*event*

Debugging

As a regular unpriveledged user

Setup console to display kernel log.
dmesg --level=debug --follow

Open a new console and access the device with jstest.
jstest /dev/input/jsX

Interact with the device and observe that data packets recieved from device are printed to kernel log.
