Check out the usb-serial-for-android project for the communication from Android to the USB device. 请查看usb-serial-for-android项目，了解从Android到USB设备的通信。 This has support for most major USB to UART Bridge devices such as a Silicon Labs, Prolific, FTDI and CDC Class devices. 它支持大多数主要的USB至UART桥接设备，例如Silicon Labs，Prolific，FTDI和CDC类设备。

You can talk to it as a serial device from your laptop computer using normal serial communications such as POSIX method for Linux or OSX or the Commuincations API for Windows . 您可以使用常规的串行通信（例如Linux或OSX的POSIX方法或Windows的Commuincations API）从便携式计算机作为串行设备与之对话。
