The USB is likely to be providing the power to the speakers, I suspect theoretically you should be able to plug the USB into a wall charger, and as long as the 2.5mm jack is plugged in, it should work fine.
Can you show us a screenshot of your device manager? Searching online for updates using Windows Update may not have got the drivers, you should have got an installation CD with the motherboard with audio drivers on it.
If you've plugged in a different soundcard, then you'll need to make sure you've installed drivers for that.
Also, as Joe said, sure the speakers are working?
