re hosting... maybe I'm mistaken.. I thought that Android's USB code behaved as a USB Host in order to mount/use a mass storage device.
I looked at the robot fans web sites and links, but being an Android neophyte (hmmm), I didn't get the big picture of how one can pass data to/from the USB port with an existing driver within the carrier-approved baseline OS.
(Bluetooth: Did that already. Bluetooth to serial to hardware to control. Works, but goal is to eliminate this wireless link.)
Android USB adapter and app allows ZX control
There are many different classes of host with different capabilities.
I'm still as unclear about what you want to accomplish as Tom Becker seems to be. If you can formulate a clear question, you might get answers at...

Jan Axelson has written a couple of books on USB so she is probably a better source of information. Try the USB forum at the above link.

I'm sorry.. let me try again, succinctly:
Goal is to exchange low speed, low volume bytes with a custom-designed device that will plug into an Android phone and take power while exchanging data. The device hasn't been designed.. because the top level approach is still unclear due to the following.
Use the drivers that come with the carrier-approved phone. Add whatever Application software, so long as the phone doesn't have to be rooted (unlocked) and risk rejection by the carrier(s). This is in a non-hobby setting where one must adhere to the carriers' policies.
This USB attachment would replace an existing Bluetooth connection method that works, but requires a battery.
