Gestures stop working after trackpad re-connection

[hw0603]

I'm using a Mac Mini M1, Monterey 12.5.

jitouch automatically launches successfully when I restart my Mac, but when the Magic Trackpad is disconnected and reconnected, the gestures set on jitouch do not work.

The only way to get the gestures to work again is to close the program and restart jitouch in preferences.
Is this an intended feature? If not, what can I do to fix this bug?

I've tried v2.79, v2.80, and v2.81, but no good

Yeah I've seen this issue as well recently. Jitouch should detect when the Magic Trackpad is attached/detached but perhaps the internal identifiers have changed.

Specifically, this code should add the listener:

I'll see about fixing it when I get the chance.

In the mean time, you can also use the terminal command killall -HUP Jitouch to send a signal to Jitouch to reload its devices without quitting.
Or, killall Jitouch will quit Jitouch and then the LaunchAgent will restart it.

I've been experiencing this issue recently as well. The thing is, my magic trackpad is always connected to the mac via cable, and I saw it in the middle of active usage of the trackpad. So I don't think this happens only on reconnections.

Hmm, that's weird. What happens if you run killall -HUP Jitouch, does it start working again? Also, can you check the log at ~/Library/Logs/com.jitouch.Jitouch.log if that happens?

Yes I use the command killall -HUP Jitouch whenever it hangs, and it works quite well.

$ cat ~/Library/Logs/com.jitouch.Jitouch.log

In the Jitouch preferences > About, can you set the logging mode to "Info"? Then the log will report which devices it is reloading. If you can, send an example of reloading after Jitouch has stopped recognizing the trackpad.

Hey, I've made a pull request that should fix this issue. Try out the debug build below and let me know how it goes.
