>From what I've seen, using a USB<->RS232 adapter is the LAST thing you want 
to do. I've had enough problems with a dedicated RS232 port! Some of the 
GMECM code ($58 in particular) is VERY fussy about the timing of chatter 
responses. USB adapters just add variable delays IME... I use ancient 'throw 
away' lap-tops with dedicated RS232 ports that I don't worry about 
losing/breaking.

I am a newbie having the same problem.  The Laptop com ports are so
difficult to setup with regard to a USB connection..  I can't get it to
connect to the ECM so I can't really do anything with this yet.  I spent
3 hours on Sunday only to get frustrated and walk away from it.

I am using an ALDLcable.com cable with the 10ohm resistor tag between A
and B and an HP laptop with USB interface.  (actually, I've tried a dell
laptop too).

Does anybody have a how to guide for the WINDOWS / COM / USB / side of
this?
