It looks like just another 2232 adapter.
Not just -- see the schematics, you'll notice
a bunch of wiring needed to support SWD as an
option in addition to JTAG.
Yep. Not
David asked me to forward his reply also to the list.

I can't say that yet ... pending SWD support in
OpenOCD needn't be Versaloon specific, because Versaloon can be OpenOCD
specific.
Actually, new JTAG driver of Versaloon in OpenOCD is only designed for
OpenOCD, vsprog uses another driver.
I can decide how to implement SWD driver in OpenOCD, and maybe it's also
different than SWD driver in
Quick update on $SUBJECT: it's come up OK for me
recently, possibly resetting or halting the
stellaris target was a key step.
I could see the TPIU, ITM, and DWT instead of
spurious NVICs. And on LPC1768, the ETM also.
Puzzling, but now less worrisome...

I've placed an order for one to have a look

Yes, lm3s3748-ek. See the user's guide. This
is one that uses a small CPLD external to the
ft2232 chip. So the schematics include just a
bit of tracing through CPLD logic...

From STM32 ZY1000 using current
master branch:
Looks OK to me. Maybe a bit thinner than
the other ROM tables I'm used to seeing,
but that could just be STM32 vs fancier
chips (OMAP3, LPC1768, etc).
Thanks -- this suggests maybe I was on the
right track to think of layout bug in luminary.

I have one here and it works very well with their software.
Maybe it could start working with ours at
some point too ... ;)

The Cortex parts (M3, A8, etc) all have ROM tables listing
resources exported to debuggers, which are displayed in
OpenOCD using the dap info command. I've seen this
work well with Luminary (LM3s3748), NXP (LPC1768),
and OMAP3 parts in the past.
However, I recently observed two Cortex-M3 parts

But OpenOCD SWD may not be quite there yet, and in any case you said

Not yet (for SWD with OpenOCD) ... only for its
JTAG mode (part of standard OpenOCD).
