@ploopy Power drainage seems to be a problem for my #ThinkPad when on battery. Need to re-plug the USB cable multiple times until it becomes detected properly. Most of the times the buttons are recognized, but the trackball isn't working. Doesn't happen if the notebook is connected to a power cord or a docking station. Had the same issue with a different #Ploopy Bean I've had my hands on.

Mostly using this device at home on my desk, so no problem here. Maybe this can be fixed in firmware?
