Another FTDI solution that also uses the Android Open Accessory mode is FTDI’s Vinculum-II (VNC2) family of ICs and modules. This is a single-chip embedded host which can be programmed to include the AOA support. In addition to the interfaces available with the FT311D IC, the Vinculum-II also includes a second USB port that can be configured as a USB host or USB device. With the second USB port of the Vinculum-II configured for host, it is possible to add USB support for traditional USB peripherals such as a barcode scanner that already uses an FTDI peripheral IC or connects as a HID peripheral.
