I have used the hub to connect a USB wireless mouse and downloaded from a camera USB card reader. Both worked although the mouse can sometimes get a little "Herky Jerky". Keep the hub as far from the laptop as you can. You must pay attention to the notification that comes with the device that warns about not plugging it into the left side laptop connectors. I also received a notification by email about this quirk, so the supplier did their very best to keep me informed. Of course, I just plugged it in there on the left side, in a hurry, and it promptly destroyed my internet connection...WTW! Mostly works fine and lets me communicate between the new laptop and my other tried and true older devices, I really like the easy fix. Don't need another $35 mousie.
