Hi, it's Annabelle. Does anybody know where I can find an A&B Switch that supports both USB and Serial Ports? The reason why I ask is because I'm eventually going to purchase the Rockbox I7 from PC Audio Labs, and my monitor is powered by a serial port connection. Also, I'm going to hook up my computer keyboard, my mouse, and both my printers to the USB ports. Does anybody have any suggestions for me?
