Since the Vinculum-II has two USB ports that can be independently configured for host or device, it is possible to combine both interface options 1 and 2 through a single chip. AOA support is available on the USB host port. Java D2xx is available through FT232 emulation on the USB device port. This solution now provides support for all Android devices, regardless of the type of USB port or power configurations. The interface on the USB device port can support a traditional PC environment, enhancing the peripheral’s usefulness even more.
