Thanks for the info. I need to think about how to do this
compactly. Maybe I could skip the desoldering part completely and just
use chain saw to remove a piece of the motherboard that has two of
these sets of two receptables? That way I would have four USB
receptables tightly mounted on a PCB and could connect pull-down
resistors to the other side, right?
