First try unplugging (and removing the battery on a laptop), press the power button for five seconds. Leave it for two minutes and try the USB again.
If that doesn't work...
Restart in Safe Mode*
Open Device Manager, click Start, and then click Control Panel. Double-click System. On the Hardware tab, click Device Manager.
Double click Universal Serial Bus Controllers/USB Root Hubs. Right click each instance underneath and uninstall the drivers. Don't worry, Windows will re-build them.
Restart normally and try again.
*Note: On start up (before Windows loads) keep tapping either F5 or F8 (be aware that some manufacturers use F8 for system recovery!) then use arrow keys to highlight 'Safe Mode with networking' and hit Enter/Return, click on a user account, enter the Administrator password (if you don't know it, there probably isn't one so leave it blank) and hit Enter/Return.

Many of the times that this has happened to me, it has been because I am missing a driver. Drivers are what allow an external device to be detected and run on any computer. So I advise looking online for a driver for the mouse on the company that made the mouse's site, usually download links can be found there, install the driver and you should be good to go.
Refresh the USB Stack
Control Panel - Device Manager - USB Serial Controllers - RIGHT CLICK on EVERYTHING and UNINSTALL
all except the category itself - REBOOT - this refreshes the drive and the USB stack
reinstall the drivers by removing the current driver, it should then recognise as a new harware & install automatically, or if you updated the driver, roll back to original or previous version
