Thanks for the feedback.  I couldn’t upload the CDC code thru USB... I got an error like “not in sync” or similar.  However, I was able to upload the code via ISP using a Sparkfun Pocket AVR Programmer that Karlis mentioned in a few of his posts (he recommended them for boot loader, but it worked for the CDC code, too).
-The board gets 5v thru the ISP and the regulator handles conversion to 3.3v properly.  
-When plugged into USB, my computer (Windows 10) shows a serial converter and a new com port.  No trackball, though I do recall seeing something like that before I had the correct FTDI drivers.
-Perhaps my RN52 is damaged — I did get it quite hot while soldering.  But I do get the “configuration completed!” message in the serial monitor window.  Is that message actually generated by a response from the RN52?
-Confirmed LEDs are inserted correctly.  Also, the RN52 is not broadcasting as discoverable.
-Also concerned that my car doesn’t recognize the bluesaab when it is plugged in, so it seems there’s more wrong than a possibly dead RN52.

Feeling like I’ve run out of ideas.  Perhaps I’ve managed to taint this board in an unusual way.  Rather than starting over and rebuilding this 5.5 board I should probably start over with the v6.0.  Alternatively, if there’s someone in the Bay Area that’s familiar with these things and willing to take a look, I’d be happy to drop my device in the mail.  I’m in Walnut Creek.
