|hi all, here's what happened, I updated my nvdia driver through drivermax and I am not sure if this caused the problem but ever since then my mouse had stop working sometimes. It was fixed by a restart but yesterday, my mouse was completely down. So I changed a new mouse but it was the same. The usb just couldn't detect the device with error message device driver and software was not successfully installed.|
I have tried everything, manually update the driver, system restore, system repair and lastly I reinstalled my win7(without reformat the hd). So apparently it is the problem of the usb ports, now it's the keyboard's turn to stop working. All other devices like bluetooth and usb wireless adapter have no problem. It turns out in between mouse and keyboard, only one of them will work.
What should I do?
