Fix for keyboard/mouse/tablet being detected as joystick in Linux.

There are several devices that, although recognized by kernel as joysticks, are not joysticks. This repository contains rules that will prevent the non-functional /dev/input/js* and /dev/input/event* devices from being recognized as joysticks.

This is just a blacklist, which will always be incomplete (until the actual bug gets fixed). Feel free to add more devices to this list.

How to install

Version that changes permissions to 0000

sudo curl -o /etc/udev/rules.d/51-these-are-not-joysticks.rules \

Version that removes the device

sudo curl -o /etc/udev/rules.d/51-these-are-not-joysticks-rm.rules \

Which version should I use?

Personally, I'd try the first version (that sets permissions to 0000) first. If it does not work or if it gives trouble for some reason, I'd try the second version (that removes the device).

The first version (that sets permissions to 0000) seems to work fine across several distros, but some distros (such as OSMC, see also issue #26) may have additional rules that end up setting the permssions back to another value. In such case, the second version (that removes the device) should work.

In the end, it's up to you, and it's about what works best for you and your system.

What's different in after_kernel_4_9/?

A patch has been accepted into Linux kernel 4.9, so that Microsoft devices will not be detected as joysticks anymore. Thus, those devices are not included in after_kernel_4_9/*. Read issue #20 for details.

How it works


A rule will match if:

  • The subsystem is input;
  • The pair idVendor and idProduct is in this list;
  • Either one of:
    • The device property ID_INPUT_JOYSTICK is set;
    • Or the device name matches js[0-9]*.


The following actions are taken on each matching rule:

It is not possible to rename a device, so NAME="not-a-joystick%n" will not work.

Learning more about udev rules


Look at the generated /dev files: ls -l /dev/input/

Unplug and plug your USB device while monitoring for kernel and udev events: udevadm monitor -p

Look for other udev rules that may interact with the same device: grep -i '\bjs\b\|joystick' /lib/udev/rules.d/* /etc/udev/rules.d/*

Testing joystick detection

These tools list and interact with all available/detected joysticks:

Bug reports and mentions

There are reports of this issue on different distros and projects.

The udev rules in this repository have been added to:

But remember that the version distributed elsewhere might be different than the version on this repository.

Known devices

For the complete list, look at script.


The best ways to contribute are by creating a new issue or by making a pull request. Make sure you mention the device name/description and the vendor/product IDs. The relevant line from lsusb output is usually enough.

This repository contains a list of devices compiled from contributions of several people. I cannot test every single device. If something does not work for you even after you have added the correct rules, please try debugging it on your own system. The output of udevadm monitor -p may prove very helpful. Also look at the output of ls -l /dev/input/.

History of this repository

After suffering with this issue for a long time, I decided to investigate possible fixes and workarounds. Then, in May 2015, after searching a lot for a solution, I've managed to create some udev rules that fixed the issue for my devices and decided to share this solution with other people. Initially, I shared the simple file at GitHub Gist. Over time, people submitted contributions through comments, and keeping that file on Gist was becoming too hard to manage.

In October 2015, I decided to move the file to this GitHub repository. That way, it will be easier to make changes, to fork, to receive notifications, and essentially to maintain it.

Ideally, the bug in the Linux kernel should be fixed, so that this repository (which is essentially just a workaround) wouldn't be needed anymore.
