AFAIK, most of USB chips (at least the ones involved here) need both the differential data pair, AND the power lines for device identification, even if running in self-powered mode.

I think it is Gordon who uses a different TI USB chip at the DAC end that needs just the differential data pair. I guess your suggestion might work in this case.
