No soldering needed, as its a skill I do not have. ;-)
That sounds like it would grill the rx line, as the FTDI breakout
board you use supplies 3.3v while the expected input is 1.8v.
As I understand it, you want to supply 3.3v to the microphone line
for detection but then run the rx/tx lines at 1.8v. I have not built
one of those cables myself yet, so I'm not sure. It probably works
using 3.3v, at least for a while, but there is a significant risk
of damaging the hw.
I have been running this setup for a while without any issues, so too
the Linaro folks in their lab. From what they tell me there have not
been any issues thus far.
/me is just a SW dude who fondles bits ;-) and not electricity.
