What if you can't recognize the mouse?

1, first look at the device Manager above the driver is abnormal, try to click on "My Computer", and then find the "Device Manager" button, open the Device Manager window to find "Universal Serial Bus controller." Then remove the option driver with the question mark and exclamation point above the Drop-down list, and then click Scan to detect hardware changes and try to reinstall the driver automatically.

2, if the above method does not work, then enter the computer security mode, and then enter Safe mode, the above driver reinstall the USB driver. Restart the computer again. See if the failure is resolved.

3, finally in the safe mode, after restarting the computer, and then into the normal system, in the C:windowssystem32 directory, first find the Drivers folder, and then create a new Drivers2 folder, Then copy the files on the Drivers folder to the Drivers2 folder, and then delete the Drivers1 folder, and change the Drivers2 folder name to Drivers1. Again to detect whether the mouse is normal.

4, of course, if the software method can not solve the problem, may be the hardware. Try replacing the USB jack. Hope to solve the problem.
