So "USB 2.0" really means "USB 2.0", and we could describe this as something such as

	LINKTYPE_USB_2_0	XXX	DLT_USB_2_0	USB 2.0, 1.1, or 1.0 packet, beginning with a PID, as described by Chapter 8 "Protocol Layer" of the Universal Serial Bus Specification Revision 2.0.

with "Universal Serial Bus Specification Revision 2.0" being a link to the USB 2.0 spec.
