[chirp_devel] Portmon doc for 64bit windows?

[Eric Shattow]

This analysis can be directly in Wireshark by writing a dissector for
your USB serial device; the Linux kernel sources tell us details of
many USB serial devices. I'll do my best to help when someone can get
this started:

wireshark-2.0.3/epan/dissectors/packet-usb-com.c

as an example of a dissector.  Also possible is to write this in LUA
language but when I started this way I discovered some unexpected
behavior / bugs in wireshark 1.9.x LUA support; maybe these are fixed
now, but for inclusion into wireshark upstream we should target the
upstream C source code tree.

Even without a dissector you should be able to apply a filter:

"usb.capdata and usb.bus_id==8 and usb.device_address==2"

where 8 and 2 are values from the Linux host in 'dmesg' or 'lsusb'
output. This gives all transactions where there is more data than the
existing USB dissectors can handle, and should be mostly the RS232
data payload we're interested in.
