I'm not familiar with udev and I would have expected that the device
manager is responsible for creating or handling device nodes. This could
also be a bug in the kernel. We have received similar bug reports [1]
[2] for games in the past.

In #714399 [3] Peter De Wachter pointed out that it might be a
longstanding kernel bug, reported as:

https://bugzilla.kernel.org/show_bug.cgi?id=28912
https://bugzilla.kernel.org/show_bug.cgi?id=37982

But there is also a way to work around this issue by blacklisting such
devices with udev rules:

https://github.com/denilsonsa/udev-joystick-blacklist

I'm not sure if someone ever intends to fix these kernel bugs. If udev
is not responsible for creating those fake joystick devices for
keyboards and mice, then please consider to blacklist the affected
devices, so that they will not be confused with joysticks.

Thanks,

Markus
