Apps How to debug USB OTG application?

[andrey2211]

I am working on an Android application which talks to external device via USB. How can I debug such an app?

Is it possible for virtual device to use real USB in OTG mode and connect to external device?

How do I wire real phone for debugging? I need my PC to be USB host for USB debugging right? So if PC is connected to phone USB port is busy. Is it possible to wire real phone to be USB host for external device while having PC debugging the app?

The adb command has a tcpip mode. I've used it and it works, but when I plug the USB OTG device in I stop getting logcat output. Maybe I'm doing it wrong, but maybe you can figure it out.
