Thanks this is what I am looking for because everyone else misunderstood that I could run software on the tablet to “host” it. I think there’s some limitation of the USB architecture that makes what I want not really possible except with some very specific computers. I understand it but at the same time I don’t understand why. You can’t output raw signals to USB in a way that something on the other end will just hear that data as pure data. There needs to be some kind of mutual agreement on protocol at the fundamental level, if that’s a sloppy way to phrase it.

Thanks I’m gonna look into this because it might be worth a small investment to be able to do this going forward with other devices.

I appreciate your reply. You got what I was asking for. I realize I was not explicit about the unique nature of my needs but you got it.
