void kbdUSBRead	(	DevicePtr	pDev,
		MOTIONPROC	motion,
		ENQUEUEPROC	enqueue,
		CHECKPROC	checkspecial,
		BLOCK	block
	)

Read an event from the pDev device. If the event is a motion event, enqueue it with the motion function. Otherwise, check for special keys with the checkspecial function and enqueue the event with the enqueue function. The block type is passed to the functions so that they may block SIGIO handling as appropriate to the caller of this function.
