I am wanting to use a set of Antec usb external sound sensitive neon lights on a non-computer project, as well as using a couple of other usb powered components in other projects, and looking to find a schematic explaining the pin designations, voltages and functions of the usb connections. Anyone know of a site that would have this and maybe other similar info? Although this isn't quite a PCBUILD question, I have been having to identify a lot of different connectors due to my current (first) pc build and the usb is about the only one I am lacking any practical info on. Hungry to learn!
