My razor naga isnt working.?

Recently just bought a razer naga mouse and it worked fine for a couple of days. I plug it into my USB port and the lights do not come on and i get the "USB devise has malfunctioned and isnt recognised" messege or something along those lines. It says theres no driver instaled but then i check under the device manager and it says that the drivers are up to date. So i download the razer updater to try and update it again,. but it says that the mouse isnt connected .Please hel
