I need to spend more quality-time with the board and uCenter. With 
hundreds of configs and subconfigs, it kind of turned into a haze before 
my eyes. I did not do this with any rigor, mainly poking and prodding. 
So it's probably worth investigating more deeply.

I did convince the ebay vendor to refund $5 of the $13 it cost, for 
selling counterfeits. What a deal! Too bad ebay has utterly no interest 
in cracking down on this sort of thing though.

Glad I had the 3B+ handy to test with, otherwise I'd probably have just 
thrown out the module.
