If I've found the correct schematic, USB power is switched using PD10 on the ZI2. This is pin 79 and is currently a normal I/O pin. Please could you try setting 79 as an output and then trying PIN(79)=0, pin(79)=1 to see which enables the USB power. SB77 should be ON

This version waggles PD10 as well as PG6 so should work on either board with the downside of losing an extra pin
