Comment(by Quozl):
John, I've checked on build 28 with q7b14, the GPIO 148 is configured as
an output, and is set high, and the MFPR is set to function 1, and the
ball number matches the schematic. I've also tried to reset the hub using
sdkit, while a USB drive was plugged in, and Sugar was displaying
contents. I observed no effects at all; no kernel messages, no change to
the USB drive LED, no difficulty accessing filesystem. This suggests that
either it isn't connected, or it has no effect on the hub.
I suspect the wakeup method used in testing is what runin is using; timed
wake.
