How to enable USB API in Android Things for Raspberry Pi 3

Question

I am working on a project that includes a Raspberry Pi 3 Module B board with Android Things OS on it. My Android application running on the Raspberry Pi3 needs to communicate with external equipment via USB. But known issues pointed out https://developer.android.com/things/preview/releases.html that the USB interface is currently disabled.

Is there a way to enable the USB API in Android Things? Any help or guidance on the same subject would be greatly appreciated! Thanks in advance!
