On one of my design, I'm using a FT4232 Quad RS232 IC. Since the design has multiple FTDI devices, I uses the Android USB Manager API to filter down by Vendor ID and product ID. After such a filter, what I get is essentially a UsbDevice. But in this case, we have multiple interfaces, which the createDeviceInfoList() call will enumerate into different devices. How can I open a specific interface on a UsbDevice using D2XX library?
