I tried using xpadneo to connect an Xbox Elite Series 2 Controller via
Bluetooth. Although the controller could be paired correctly, it was not usable
in any way (while connecting via USB worked perfectly of course).

After inspecting the `xpadneo-kmp-default` package, it seems only the driver
binary itself is installed:

$ rpm -ql xpadneo-kmp-default 
/usr/lib/modules/6.8.9-1-default
/usr/lib/modules/6.8.9-1-default/updates
/usr/lib/modules/6.8.9-1-default/updates/hid-xpadneo.ko

In the source repository however, some files are provided for modprobe and
udev:
https://github.com/atar-axis/xpadneo/tree/master/hid-xpadneo

Manually adding the files inside the `etc-modeprobe.d` and `etc-udev-rules.d`
folder of the  repo fixed the issue; which makes me think they should be
included in the `xpadneo-kmp-*` packages.
