Have this adapter now for two months as an extension of my tablet (MS Pro surface1 => 1 USB3 port) in use. The USB 3 hub works immediately after plug in plug-and-play manner. With the inserted Blutetooth dongle from the mouse and keyboard there are no problems. With the LAN Adapter There were initially problems, he was recognized shortly after connecting and then flew out of the device manager to get out again, resulting in unsightly breakers in the network connection. Apparently came with the Windows 8.1 installation, a not yet mature drivers. Even the adapter enclosed driver behaved no better. Fortunately on the side of the chip manufacturer (ASIX AX88179) a newer driver also fast Gigabit-LAN connection for stationary use of the tablets was available, after its installation now works stable. In order for the adapter deserves its 5 stars.
