thanks for your reply, Greg.

I tried what you have suggested. Unfortunately, this doesn't change anything.
What confuses me a bit is that theses USB disconnects do not appear as soon as I read what the tablet provides.
Could it be that the usb driver doesn't check for a connect status change while there's a process reading /dev/input/{mouse,event}? so that I do not see these disconnects while reading the tablet data?
Or could it be that something prevents the tablet from disconnecting itself when a process is reading the tablet data?
