My laptop have 2 usb ports, but one is broken, so I use an USB hub in the another good USB port. In that USB hub, I use a mouse and keyboard. Suddenly, that USB port doesn't detects the mouse and keyboard (even with the light of the hub is on), and the only solution that I found is restarting the laptop. But just some minutes and the keyboard and mouse goes undetected again...

So, I wonder if there is some method/software/etc to "restart/repair" the USB port without restart the PC.

Thanks for all!
