I was looking for something like this, but I couldn't find a file "disable" or something similarly obvious :-).

Or into a different hub, or directly into the computer? Everything works as expected. I've also tried booting windows for a bit, and there things are even worse. It won't properly install the tablet, let alone let me use it. I guess this means there is indeed something broken in the hardware (Most likely the connection between the hubs, then). I'll just send the hub back and hope that I get a new one which does work :-) Gr. Matthijs
