Does it also take power from USB?

I assume this is an "active" adapter, since you're converting Analog (VGA) to Digital (HDMI). It would have to be, to get any sort of display - and, while non-powered adapters are sold (for some reason), they're not exactly reliable. They really should have additional power, either from the wall or from USB.
