Hoglet stops responding but still connected

I've been having a recurring problem with my Hoglet and Hog4PC (v3.17.1 (b 3363)) lately. During the event, it suddenly stops responding to the buttons. But in the ControlPanel -> Wings it is still listed and when you press the lightbulb all the LEDs of the Hoglet light up. That means it's still connected.

It's happened several times in the last few 8 hour events. So far the error is not reproducible. The buttons only respond again when I unplug the USB cable and plug it back into the PC.

Does anyone know what the problem is or what I could try?

Thank you <span>:smile:</span>
