Question about Razer Mamba Tournament Edition

As far as I can see, the Mamba Elite contains comparable resolutions, it is probably a bit lighter than the Mamba Tournament. I also had the corresponding keyboard, but had to switch to Logitech due to technical problems. The Mamba was a cool mouse, cool accessories, really fun. It was fast and precise. But unfortunately the USB no longer recognised the mouse. I bought a replacement. It worked great until the USB port stopped working on that one too. I connected the Logitech to the same port and, lo and behold, no problems (G-403).
