You are quite welcome.

So it would seem.

Ah.

I have the capability of compiling firmware and/or application code
for Linux for testing.  I'm fluent in C so I'm not just limited to
monkey testing.  I can poke around in the code and make my own
(thoughtful) mods.  (And I'm offering to be an active part of the
testing process).

I happened to purchase mine with the IEEE connector but my soldering
skills are fine.

Since you asked Ville, let me say that my cable is a 2m-long lab-grade
shielded IEEE cable that I got from work (10+ years ago) when they
were tossing old test equipment.  It appears to be new or nearly new.
I have other cables as well.  I have it connected as Laptop<->USB Mini
cable<->Zoomfloppy<->2m IEEE cable<->2031.  Nothing else on the bus.

Gotcha.  Just running through the gamut.  I'm not surprised it didn't work.

I can check that easily.
