The use of the Chromebook could not be simpler: USB plugs into the laptop, network cable into the hub, and immediately the connection as if DHCP is on the network.
On Windows only, the hub function works without driver installation. Therefore, the hub poses as CD drive where there is a driver. This then I could install on my PC with Windows 7 Ultimate 64 bit within a few seconds. It came after the installation an error message that the installation may not have been successful, but it then worked immediately everything as it should. So typical Windows problems for the Hub can not really what.
The Ethernet reached me almost the full 1000 Mbit / s. Have it measured iPerf and copied as a practical test a large file from my Media Center PC via SMB and the difference to the built-in Ethernet from my EVGA Z87 FTW are very few MB / s, so I could transfer more than 115 MB / s.
The hub function does not seem to thwart. With my SanDisk Cruzer Extreme 64GB, the same values beyond 170MB / s were achieved as directly on the port. Of course, all USB and Ethernet port must share the available bandwidth, so while leveraging bottlenecks could arise, but should probably occur in practice rare.
