text: how does usb sound work? i'm gonna buy a desktop speaker, but before i do i want to know how it would work because it is a usb speaker(thats what the specs said).    so i just wanna know how does it work and if it would work with any computer.  thanks for you answer. usually the speaker is plugged in to the sound card but if you have to plug the speaker  in to usb port, make sure you get the driver for the speaker.
