The USB header in a pcap capture file or in a section of a pcap-ng capture file
must be in the same byte order as the pcap capture file or the section of the
pcap-ng capture file.  libpcap/WinPcap makes that happen, by, when you read a
packet from a file, byte-swapping the multi-byte integral quantities in the
header if the pcap file/pcap-ng section is in the opposite byte order from the
host reading the file.  We would need to do the same.

That would mean that the USB dissector should fetch multi-byte integral
quantities with, for example, tvb_memcpy(), rather than tvb_get_ routines.
