The Hub was delivered quickly and has the first few days also works perfectly. Unfortunately, after the problems started. The plugged devices were indeed still recognized all but the connection was not stable. Time and again individual devices were suddenly logged out of itself and then immediately logged by itself. What's especially bad when you're working with external hard drives and they are currently writing on. This means then inevitably data loss. The Hub has been tested by me on 3 other computers where he showed all behave this strange. Whether this hub generally after some time get these problems or if I've just caught a Monday model to be seen. I still have another stroke from the series of works without any problems so far.
