So I have a usb otg cable and the android tv box sees the usb storage and asks to format it. When I format to external storage it formats and says it is ejected. I never am able to mount the device. When I format for internal storage it formats the drive then says it is unsupported. Is there no way to actually use usb storage drives for this device? I have tried both an otg cable and otg hub as well as a 3amp 5v power supply.
I'm running into the same issue, tried several types of drives and formats. no luck.
