Ok , I've uninstalled ALL of the mouse's, unplugged the mouse I was using and restarted the pc , then I plugged in the M65 PRO RGB mouse, still not working, Used the keyboard to navigate to the device MGR and see that the M65 is there again as an HID- compliant mouse as well as the Microsoft PS/2 mouse which I just disabled along with the Microsoft PS/2 keyboard both of which were hidden thinking maybe its conflicting , still nothing, So I plug in my old mouse that works and here I am Dazed and confused, and getting no help from anyone here . WTF ???
