Very obscure controller issue

Hey all,
up until a couple days ago, I’ve used a Nintendo Switch Pro controller together with joycond-cemuhook to get controller motion data to the games that support it. Sadly, after upgrading to kernel 5.17.8, this stopped working. The program is now giving me the following stacktrace when launching it:

Traceback (most recent call last):
  File "/usr/lib/joycond-cemuhook-git/", line 800, in <module>

dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method Refresh is not implemented on interface org.freedesktop.UPower.Device

The error seems strange to me, since according to the DBus documentation, the method should exist. Is there something wrong with my kernel?

In case you need more details, I’ve opened up an issue on the repo with more info

Have you rebuilt joycond?

I’ve rebuilt both joycond-git and joycond-cemuhook-git now, with no success

Try the LTS kernel.

Running on 5.15.41-1-lts now, same issue
Very strange

Well, out of ideas, sorry, no access to the hardware.

Still, thank you for trying

Downgrading upower from 0.99.18-1 to 0.99.17-1 fixed it
Credits for the find go to @danielsuarez369
