Hello Bill,

I have one of the modules that I built without the 10K resistor and the debug works just fine.  However, I also have another module which still has the 10K resistor in place (on my sons robot) and the debug also seems to work ok too.  Neither one worked on my first attempt.  Why, because I have the development tools installed on a couple systems and the laptop I am using was still running the SX-key software 3.2.3  It found the USB SX-key and could program the chip.  When using the older version it would sometimes pop up COM port not found and all the debug options were grayed out.  After I downloaded the latest v3.3.0 version and installed it that fixed the problem.  It also updated some of the FTDI USB drivers on the system.

Are you using the latest v3.3.0 or an older version of the software?  If you have the latest do you have more than one USB SX-Key?  Perhaps some are more picky about the 10K resistor being installed than others.
