I would like to identify a USB keyboard uniquely(something equivalent to unique mac-id for the Ethernet cards) on a computer. Does the USB HID profile has a support for such identification ? If so what is the field called ? I understand that VID and PID uniquely identify a make of keyboard from a vendor, but I am looking forward to identifying each keyboard separately.
PS : Asking the question on Elex SE, since I would have to implement this USB profile on AVR32.
