After removing the chip, and looking around under magnification, I noticed a tiny sliver of metal across... you guessed it, the two middle pins on the backside of the USB connector. The SCL and SDA pins. Everything works now! Unfortunately, I don't know if it got there while I was desoldering, or before, so I have no way of confirming that it was or wasn't the chip, but either way it is back to normal!
But Westworld is coming on and I have to wait till tomorrow to keep wiring :-)
