Bc2000 (for the BCF2000 & BCR2000)

Hiya

Sorry for the dumb question but im tempted to buy one and was
wondering if anyone could answer a quick question... 

Is the bcf2000 able to run powered by USB rather than using the mains
adapter? 
Im hoping it might run off usb as im running out of plug sockets!! :)
but im guessing that the fader motors might use too much power so im
doubtfull, so... whats it to be?

Cheers

Rich
