Do countless years of computer engineers, incredibly today USB problems, it took me one hours to solve.

The problem is that the system is used, the USB mouse is gone, then the system blue screen, see is dump RAM. I was too lazy to wait and restarted the system.

Then, after the system restarts, the mouse is lost. I can't find it anymore.

Helpless, find PS2 mouse, point to open Device Manager, incredibly USB Root hub has yellow exclamation mark, the general Huang number is no driver or driver error caused.

What to do. Download a few drivers, incredibly all say I have used the simple.

Baidu One, see someone uninstall, re-scan hardware changes, try a bit, sure enough OK.

Ashamed.
