...and if my optical mouse is plugged into it, the notebook won't boot. The reason that I got this thing is so that I could plug my new jump drive into it without having to close the screen and move it around to get to the ports on the back. It will boot with the digicam hooked to it and with the jump drive fine. Right now, I have two ports on the notebook; using the hub for one and the optial mouse into the other one. What gives? Is it junk? Or is this common? I still have the packaging and receipt for it. A Walmart special made by Cyberpower (around 20.00 bucks). Thanks in advance. Wanna kill these ads? We can help!
