Mouse not recognized/ mouse port not wor...

I kept hold about 30 seconds the blue light button on the USB controller device and it worked!. I guess that's the way to sinchronize both the mouse and the USB controller of the mouse. Ramón.

I had the same problem with my new optical mouse. I have a wireless USB mouse, but was tired of changing batteries on it and so I bought a new corded optical mouse that uses a PS2 port. The new mouse didn't work and I searched the entire web endlessly looking for a solution and almost giving up on it.

Any way here is the solution I found that fixed it for me:

1) Control Panel -> Systems -> Hardware -> Device Manager

2) In Device Manger window go to the View menu and select Show hidden devices

3) under Mice and other pointing devices, for me, there was a yellow question mark next to PS2 port. After I right click and uninstalled the PS2 port (with the yellow question mark next to it), my computer automatically shut down and rebooted. I was able to use my optical mouse in the PS2 port afterwards.

I got the solution from another site. It may or may not work for you.

Hi Sir
One suggestion that you could try is this first go into control panel if you have XP when it opens left click Appearance and themes when this box opens you can see a small box at the top left hand side in it you can see mouse pointers open this and you may find how toreset your mous defaults
Hope this helps

Get back if it does not

ok my sister just told me her mouse in not working tried 2 other mouses still not working...any ideas

I guess your optical mouse is Ps/2 type optical. I had the same problem.

I bet your new mouse is of 1000 dpi.

Then simply change the DPI settings of your screen:

right click on desktop
go to settings
Go to advanced settings.
Change the dpi setting

and restart the system.

Try this for different DPI settings and one will definitely work.

Hope this helps.

I moved the computer, which worked fine, and unplugged all cords. When I reassembled the computer and plugged the mouse cord into the port on the tower I realized that the holes for the prongs on the back are very battered. The mouse will not work on the computer now. Any solutions to get it to fit snug?
