It is beautiful already, unfortunately, "weaves" the Magic Mouse once the hub with the Mac mini (Late 2012) is connected after a while. If you separate the hub again by the device, the mouse works again as expected. Unfortunately, no reasonable positioning further away the mouse is due to the relatively short connection cable with me possible, so I'll have to send back the unit. The problem seems to know I'm going to try a hub with the VL812-B2 chipset.
