What exactly is its return value of openAccessory?

I'm struggling with resume of my Android App when connected to USB accessory.

Obviously my ParcelFileDescriptor is null, and the method openAccessory() doesn't return anything when I call it onResume().

Anybody experienced that, yet?

Seems to be fixed, I had unread messages in the USB pipe.

The USB accessory did not read the sent messages from Android.

That's why the App couldn't get a new ParcelFileDescriptor from onResume().
