  • Ferrite beads are used to suppress high-frequency noise. Most USB cords I’ve seen loop around a big one in the cord itself (they’re those big round things near one of the ends). I suppose FTDI recommends them for the USB cords that don’t have one.
    Even if the cord doesn’t have one, and there isn’t one on the board, doesn’t a small capacitor between ground and supply do the same thing?

No public wish lists :(
