Hi! I'm curious about some details in the protocol used by USB mice. A cursory look at the "Device Class Definition for HID 1.11" documents tells me (note this is the first USB technical document I ever read) that a mouse can tell the host the format (the protocol) used to report data (movement, button state etc.). Also a quick look into linuxv2.6.25/drivers/hid/usbhid/usbmouse.c suggests that 8 bits are used for position. So my questions are: - is the position data always 8 bits wide ? - when are reports sent ? Are they polled by host ? Or sent by the device on its own ?
