I got it, sorry. You have to desolder the USB connector from the CPU
board on mine. The USB connector is fastened to the top with the two
tabs, plus all 4 USB lines (of course) -- that is what was holding it
on. It was also soldered to the bottom board for no particular
purpose it seems. There are two mounting holes and 4 through holes on
the bottom (CPU) board that look like they are intended for mounting
the USB connector, but the connector is mounted so that its pins go
into holes on the top board. Perhaps they had an idea of mounting the
USB connector upside down?
