So i got my mx revolution mouse today and charged it up and tried to use it by plugging the usb receiver in the back of my iMac (intel c2d osx 10.5.3) then i turned on the mouse and i got nothing, no movement, no tracking, no clicking. So then I tried to install Logitechs software on their website the LCC and the Connection utility. Still nothing. So then i uninstalled the logitech stuff and tried steer mouse still no function at all. So I finally test this on my windows machines thinking maybe its a Mac issue still tried just plugging it in nothing then installed the windows stuff and still nothing. This is ridiculous. What is going on.
