Warning!
Peripheral USB devices can be connected to the USB interfaces. Due to the vast
number of USB devices available on the market, B&R cannot guarantee their
performance. B&R does assure the performance of all USB devices that they
provide.

Because of general PC specifications, this interface should be handled with extreme
care with regard to EMC, location of cables, etc.
