BeagleBoard Black USB-Host on Android


I have a BBB working with Android.(5V 2A power supply)
There is a Software on it collecting data from the USB-Port, my problem is that the USB-Host isn´t working on Android. (It should be working on Linux)
When i plug in my phone for example it is loading but nothing else works.
My question is: Is there any driver i can istall or anything else i could do to make it work?

Thanks a lot for reading and helping :slight_smile:
