--- Comment #10 from wsb...@eclipso.ch ---
I'm a total newbie regarding Wireshark (and definitively not seasoned
enough in Lua), but I wanted to debug communication between an Olimex
ARM-USB-OCD-H JTAG/SWD adapter and a connected microcontroller. As no
such dissector seemed to be available, I wrote a dissector for FTDI
chips in MPSSE mode.
As the FTDI documentation is only /seemingly/ complete (or my Google-fu
sucks) and my resources are limited, a few things had to be guessed,
and it probably contains a bug or two (none yet noticed, though). And
it lacks the knowledge whether the FTDI chip is in MPSSE or some other
mode, that mode switching protocol does not seem to be documented and
has to be decoded by someone else, maybe in a higher-level dissector.
Furthermore, I'm probably not using the Wireshark API perfectly in some
details, as I was too eager to get things done than read lengthy API
docs. :-}
Today, I came across this bug report, which stated a lack of an
FTDI-MPSSE dissector, so I wanted to contribute my code in the hope
it might be helpful (although it is written in Lua) in some way.
And hoping someone can use it to write an SWD dissector. :-)

Attachment of captured communication between OpenOCD and an
Atmel/Microchip SAMD target follows.
