Found it, pins 91-94 (Table C-2), i.e. USBVC1 (2X), USBDP1, USBDN.

Any suggestion for adding these drivers in? It would be interesting to
add a USB port to the small port replicator ("I/O Adapter") if at all
possible....
I wonder if there is some sort of HW handshaking needed to initialize
USB; if so, the chips in the EPR might take care of this and w/o an EPR
USB simply won't work.
