Driver not working on Fedora 37

[marco-calautti]

I have a PS4 GHL guitar with the dongle, and I have installed the driver on my Fedora 37 machine. I am quite sure the driver is loaded when I connect the dongle as lsmod shows it, when I connect the dongle.

The problem is that when I pair the guitar with the dongle, it pairs for a second, but then the guitar resets with slow blinking leds.

Clearly, the driver is doing something, since when I pair the guitar to the dongle, when this is connected to any other arbitrary device, the guitar pairs no problem, but of course that device does not know what to do with the dongle.

I think I have found the problem. It seems that hid-ghlive has a conflict with the module hid_sony. If both are loaded, the guitar is not working. If I rmmod hid_sony, everything works fine.

The procedure I find works 100% of the time is:
sudo rmmod hid_sony
Disconnect the usb dongle and reconnect it.
Sync the guitar.
Optionally re-enable hid_sony.

I guess there could be some magic trick with udev rules to actually mask the device from the hid_sony module.

Reporting back from more experiments. It seems the issue occurs only if the dongle is already connected to the computer beforing booting up linux. If instead, I boot up my machine, and THEN connect the dongle, everything works fine, even with hid_sony enabled.
So, my explanation is simply that the udev rules you provide are only triggered when the device is added (ACTION="add"), but when the dongle is connected on boot, nothing triggers the "added" event, and thus, the dongle is already stolen by other modules.
