"The mouse is a bit strange - it has two logical "interfaces" for the USB receiver/transmitter. They are on the same plug, but they are treated as separate devices by the Linux USB subsystem. The first USB interface is the normal mouse device - it has the X/Y motion, the normal buttons and the scrollwheel. The five buttons down the left edge (Vol +, Vol -, Mute, Email and IM) are on the second interface, which probably has the additional features like battery status as well as the indicator LEDs for Email and IM."
