My notebook served as Master and various peripheral devices as a slave, has initially worked right away. But after about an hour of complete failure, the continuous current leading outlets were affected. There's nothing left, I guess that the circuit internally has an error.
The "Resettable circuit breaker" described in the manual does not exist, so could, as described, a reset is not done!
Very unfortunate that device has pleased me very well. Delivery of Amazon as always "good" but you have to take a box where nearly a piano fits in? :-)
