To clarify - as I understand it the likely power draw required for the
SC* to be awake enough to do USB suspend negotiations is rather high.
Plus it'd require a 5V source alive all the time.

Very insane, and sorry if I was unclear.
I was suggesting simply pulling the existing debug connector, replacing
it with a similar, much more robust one.
20 way 0.5mm FPC connectors are available off-the-shelf inexpensively.
This would make it useful for expansion, in addition to its primary
purpose, in a way that the existing one is not.
