Actually...oh, this is quite embarrassing... I had it connected to a USB connection that was not working ( I have quite a bunch of USB connections from my moterboard, the ones intended for the front panel on the case do not work the way they should) At first I did not think of checking this as I had read the review, and was half expecting there to be something wrong with the hub on the monitor...
The good part is that there was absolutely nothing wrong with the hub on the monitor itself, which could be of interest for the ones planning to get one :]
