The HID Nintendo kernel driver exposes 2 evdev devices, one for the buttons and another (IMU) for the accelerators/gyroscopes. Do note that Joy-Cons will have 2 devices each (4 in total). | The HID Nintendo kernel driver exposes 2 evdev devices, one for the buttons and another (IMU) for the accelerators/gyroscopes.

The IMU input device does not automatically get tagged with `uaccess` while the "regular" device is. If you do not see an IMU device listed in Dolphin's devicelist add the following udev rule to /etc/udev/rules.f/99-hidnintendo.rules. reload udev rules with "udevadm control --reload-rules" and reconnect the device(s). | |||

It took me a bit of time figuring out which axis corresponds with the right motion control in dolphin. '''These axis might change in the future when evdev standardizes them. | It took me a bit of time figuring out which axis corresponds with the right motion control in dolphin.
