I just checked mine and it draws only 2 mA of current at 5 VDC when
connected to a USB 2.0 port on my PC. This is probably not enough to
actually run the camera, but may power the USB interface circuitry inside. I
find that with the speed of the download of pictures with USB 2.0, I'm not
bothering with using my card reader, but instead just plug in the camera and
download using the PC control. While it's kind of cool to let the camera
control the download by pressing the bright blue button and having all the
shots be previewed full-screen as it goes, using computer controlled
download without the preview is way faster. Either way is quite fast with
USB 2.0.

Like many digital cameras, the S2 IS has an external power jack on the
side - right next to the USB jack. You can buy a Canon or after-market power
supply for it. You could also fashion your own power pack, if you are handy
with that sort of thing.
