The production quality of Xytek hub is dibasic. 4 of the 5 USB ports are switched on, the 5th on the short side has probably also a charging function. As a user of a SonyVaio Z13 I have to outsource equipment with only 2 USB ports USB. As a frequent traveler to the laptop from work to take with customers was the basic idea: Peripheral just leave the hub, and then connect only return just hub on laptop. When using an external drive with its own Energieersorgung and USB flash drive there with the Xystek hub no problems. My USB microphone has basically get after initial power no power to let the experiment my Logitech mouse G500 mouse running about has not worked, every second was here no current on the mouse - absolutely unusable. I do not know myself so well with the use of a mouse at a stroke from, perhaps here is yes generally discouraged them, but that would definitely micro run externally. Returns and now looking for a hub that, if possible, mouse and microphone can run.
