Hi,
· What do you mean by ‘the other one mouse is working in the laptop’? Did you get a new mouse or just asking whether you have to exchange the mouse?
· Was this mouse working in your laptop before?
· What happens when you plug-in the USB mouse? Do you get an error message?
· Who is the manufacturer of the mouse and what is the model?
Step 1:
I would suggest you to plug the USB mouse in another USB slot and check whether the mouse is working.
Step 2:
Check whether the mouse is compatible with Windows 7. Check the link mentioned below.

Step 3:
Check in the manufacturer’s website for the latest drivers and download and install the driver on the system.
For further reference check the article mentioned below.

Step 4:
It might be that the USB drivers would have gone corrupt. I would suggest you to uninstall the drivers from the device manager and let windows reinstall it when the system starts up. Follow the steps mentioned below.
a. Click on Start menu and type device manger in the start search box and press Enter.
b. Click on the USB (Universal serial bus controllers) to expand the list and delete the drivers that are installed on the system.
c. Close device manager and restart the computer.
d. Let windows install the drivers for the USB ports automatically.
e. Once you have reinstalled the drivers, connect the camera and check whether you are able to connect to the system or not.
