Joycond cannot find my joycon after bluetooth connected.

[DasCrystal]

My system is Fedora 39 Workstation (Kernel Version: 6.6.8-200.fc39.x86_64), with conditions below:

• Kernel Module "hid_nx" is installed
  
• "joycond" install and enabled
  
• Joycon connected
  

But joycon didn't vibrate, the led on it not changed. Couldn't see in the yuzu, either.
(It's works good on windows (on same computer) with BetterJoy, so it shouldn't be a hardware problem.)

And in joycond service, it just stuck at "adding epoll_subscriber: fd=4", no further react.

If you need more information, please tell me.

EDIT: With state above, the connection with joycon will keep about 10 to 30 seconds, then disconnect, due to the automatic power off of joycon.

same here on arch, kernel 6.7.1

Hello,

Are lights on your joycon moving from left to right? If yes, then you might be able to resolve the problem same way I did by following steps from this comment: bluez/bluez#673 (comment)

First, thanks to @erudic for providing a great approch for this issue.
Although that way isn't working for me, but int the same issue page, I found a resolution below:

Set these configs: (sudo vi or something else, and save them)
"UserspaceHID=true", in "/etc/bluetooth/input.conf"
"ClassicBondedOnly=false", also in "/etc/bluetooth/input.conf"
"FastConnectable = true" in "/etc/bluetooth/main.conf"

Then reboot.

And you might found your Joy-Con Works again!
This worked for me.
