CheckForceFeedback

This page describes how to check if force-feedback is enabled and working on your system.

Prerequisites

Compile all utils in ff-utils, simply type "make"
Use evtest /dev/input/eventX (replace X by some number) to find which /dev/input/event file corresponds to your device.
If you are still not sure, which file corresponds to the device, try cat /proc/bus/input/devices to list all of the devices including descriptions.
Run fftest <dev> or ffcfstress -d <dev>, where <dev> must be replaced by the device you found in the previous step.
Notice that fftest may not work for all devices.
