Description Sujai Edwin Moses 2008-01-07 08:30:00 UTC

I am getting negative values of y-axis when i move the mouse upwards. Is this a problem with the mouse or normal? if normal, can you tell me the co-ordinate system used by the mouse?

This is perfectly normal. For details about the coordinate system please see 
chapter 5.9 of the HID spec. You can find it here:
