Michael,

Please don't shout so loud, this is bad form. I am in the know how the USB protocol works and I know what is host device and what is slave device.

Back to the question. I think there is some kind of misunderstanding of my post. As I said before the original poster can use CP2101EK wasting his $50 OR he can use the software solution instead of using CP2101EK wasting about $10. That's all what I said. I hope it's clear now. Or do you have some private to me?

And one more thing about software solution. It is impressed that someone can send and recieve the packets in accordance with USB protocol at 1.5 Mbaude rate, isn't it? Perhaps next time somebody else can write the host device software (if only not in whole volume).

Be of good cheer!
George
