So, I'm not really sure if this a hardware issue or what, but I'm having some problems with a wireless USB mouse that I have. I'm trying to use it with my Asus Zenbook UX31. When I plug the USB receiver directly into the left-hand USB port, it does not work, but it does work when I plug it into the right-hand USB port. Futhermore, when I plug a USB hub into the left-hand port, and then plug the USB receiver for the mouse into that, everything works fine. I know this is kind of a shot in the dark, but does anyone know what might be causing this problem or how I could fix it?
