	Reduce the number of callback processes to 4 per
	USB controller. There are two rough categories:
	1) Giant locked USB transfers.
	2) Non-Giant locked USB transfers.
	On a real system with many USB devices plugged in the
	number of processes reported by "ps auxw | grep USBPROC"
	was reduced from 40 to 18.
