Thanks recommending the cable vs software. I was planning to purchase a coupler AND use software to switch mode.

Would something like this work?

It's not clear to me what is required to get OTG to automatically switch USB modes. For example, is it enough to just get the connectors right, or is there something else special that needs to be done?

Please note, I have an N800, so I think that means I need a miniUSB instead of microUSB.

Thanks!
