Ok, I modified my adapter to match the real wiggler pinout, and changed 
to a 74LCX245 buffer - still no success.
Upgrading from SVN version 175 to 178 made it work!

I can now attach and single-step both with my own adapter as well as 
with the Altium universal JTAG cable.
I will provide a working schematic as soon as I have time to draw a 
useable version.

What is the preferred method to submit patches?

Found them now. However, I am still looking for a sample config for the 
STR9-comStick.
