I am here again for some help. I have bought the Targus 2.0 4 Port USB hub and that is not working with my computer that is running the Windows 8 64 bit. I normally connect the wireless mouse, one usb keyboard along with the iPhone cable. This is the reason that I purchased the hub. Some of the times it works great but some of the times it shows problem to connect to the USB hub. Please help me to get the issue resolved as soon as possible.
