I'm sorry, I completely misunderstood your question. So, yes, you have to have a physical Roku device in order to develop and test your channel. Unless your channel uses USB, you won't need specifically to have a player with USB. Even our least expensive device should be fine for developing a channel. I will note that you will probably want to avoid the new Streaming Stick (I think the MHL version of the Streaming Stick does support SDTV mode) and the Roku3 as development devices as they do not support SDTV mode so you will not be fully able to test your channel if you use one of those.
