Hey all,

I'm working on a new design using USB 0 with otg/host/device functionality. I want the device to be bus powered or powered off a DC input voltage from a barrel jack. The reference boards (Xplorer) have a Ti USB power switch with ferrite isolation, is this overkill? I'm only using a single USB port and I want to be able to have the board run off USB or DC input and have it switch by itself. What is everyone doing for USB on their custom PCBs?
