Default USB power

I have a question that's been bugging me for weeks:
Can I modify a USB powered DAC to accept a discrete power supply (a proper linear regulated) ?
Basically I'm thinking of splitting the usb plug in two - one for the USB signal alone and the second one for power fed by the psu.

The unit under consideration is a Nuforce uDAC.
