Hot plugging the USB interface may cause hardware damage
If the USB interface is being hot-plugged (connecting while the power supply is on), the possibly high
potential differences of the two power supplies of controller and PC/Notebook can lead to damaged
hardware.
• Avoid potential differences between the power supply of controller and PC/Notebook or, if possible,
balance them.
• Insert the USB connector first, then switch on the power supply of the controller.
