Every time I shut down Ubuntu 14.04 LTS and then boot up into Windows 7, my mouse and keyboard don't work until the next time I get into Windows (after pressing reset button). This is quite annoying. How do I fix this?  :unsure:

. . . boot up into Windows 7, my mouse and keyboard don't work until . . . after pressing reset button . . . 

 

I have encountered this on Windows computers that do not have Linux installed.

 

The issue is that Windows does not recognize the "Human Interface" device needed to use the USB mouse or keyboard.  

 

In some cases, simply waiting for Windows to auto detect the hardware, and activate the drivers is enough.  Although I have seen machines take up to 5 min for this to happen.  In other cases, it just does not happen or takes even longer.  (After 5 min I will just reboot the machine.)

 

I suggest the following, which cures Windows of not recognizing any USB device correctly.

 

Shut down, and power off.

Unplug the AC power and wait 30 to 60 seconds for any capacitors to discharge.

Plug the computer back in and boot it up again.

Windows should now refresh all USB devices on boot up.

 

Cheers!

 

Naught.
