re-install the drivers for your device.

i should reinstal his driver just to make sure is working properly,you can check in start-my computer-rightclick manage -device manager- usb then click on action button and Scan for hardware changes.

just check the usb or ps2 port is working properly,, or else check it with some other PC,, to make sure,, the problem exists in mouse,, or else in your PC usb ps2 ports..

Hello there:
if you have tried to remove the usb from the computer and turn off the computer and restart than install it again and you can also try to put it in different r usb port it may recvognise it that way too.
Otherwise go to device manager and uninstall it andthan click on scan for hardware changes and it will reinstall the drivers for you again ok?
hope that this helps and dont forget to rate this soultion for me it helps me out too.

Did you try to reboot?
Do you have an optical mouse? (if yes: is the red light on?
(Then the mouse is recognized and you must configure your mouse options)
Did you try to connect your USB mouse to another connector?
Or if PS2 connector: Turn of the pc and connect the mouse and power on.
Did you install a new driver? (then uninstall this driver)
Try looking for the most recent mouse driver on the manufacturer site.

I fixed an MS wireless mouse that was not responding by pressing the button on the receiver while it was connected to a USB port & then pressing the button on the mouse. Worked fine after that.

After reading on Microsoft about replacing the batteries, down loading drivers and "press the button on the receiver and the connect button the receiver" - I got frustrated and almost gave it flight. Then my wife stepped in and realized that there was a green reset button on the USB connector as well. (who knew?) SO.... you press the green light (which is a button) and release it.... should blink. Then go to THE MOUSE portion and press the connect button for 5 seconds or so.... and wala...... One mouse that plays again! This ones gonna cost me! :) I hope this one works for ya!

I have similar problem. 2 inland KVM's (both have PS2 inputs, one has USB outputs) do not light or recognize my usb mouse with a PS2 adapter. They do recognize a PS2 ball mouse on the KVM's however. One of the computers (Sony vaio 1.5 GHz) does recognize a usb mouse with adapter on 2 other KVM's (Old Belkin and a Trendnet) (the second computer I have not tried in those configurations). Next I will try an optical mouse with a PS2 fitting. That did work with a fifth KVM at an auto business last week.

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.

Make sure its driver on the mouse is working fine and that windows finds it right click on MY Computer then go to hardware, device manager and right click on Mouse and see if it is installed correctly try reinstalling driver for that mouse.
