There are many separate issues here, let's start with this: For Nexus 7 over USB you *have* to use OpenAccessory (i.e. turn USB debugging off). Since you got to the point where you're getting the accessory dialog, this means that you haven't installed an app that was compiled to work in accessory mode. Both apps that you've mentioned where not developed by me and I do not know what they contain. As a proper reference, please start with the precompiled HelloIOIO.apk that is provided with the official IOIO software bundle. Since your IOIO v1 is running app firmware v4.00 you'd need to take the Android app from the v4.x bundle. Your IOIO-OTG is running app firmware v3.30 so you'd need to take the Android app for the v3.x bundle for it. It would be easier to simply upgrade both to v5.00 and use the v5.x software. There have been quite a few bug fixes in this revision that you probably want to be using. Last, the fact that you're IOIO-OTG doesn't work with the Nexus may indicate that you're connecting the USB cable in the wrong direction. With the v5.x software, you can use the IOIO as either device (the Android provides power) or host (the IOIO charges the Android). I would start with the IOIO as host. Make sure the trim-pot is fully clockwise too.
