Widnows 作为 Android USB 附件的实现

原理：通过 WinUSB 发送 adk 协议，将 Android USB 设置为附件模式后进行数据通信

主要用作在硬件实现前Android软件的调试工作

1. 下载 http://www.lvr.com/files/winusb_cs_20.zip ，该软件实现了winusb 控制

2. WinUsbDevice.cs 增加方法，并在主界面添加调用按钮

internal  Boolean DoControlTransfer(IntPtr winUsbHandle)
        {
            UInt32 bytesReturned = 0;
            Byte[] dataStage =  new  Byte[2];
            try
            {
                // 发送51
                NativeMethods.WINUSB_SETUP_PACKET setupPacket;
                setupPacket.RequestType = 0XC0;
                setupPacket.Request = 51;
                setupPacket.Index = 0;
                setupPacket.Length = Convert.ToUInt16(dataStage.Length);
                setupPacket.Value = 0;
                if (!(NativeMethods.WinUsb_ControlTransfer(winUsbHandle, setupPacket, dataStage, Convert.ToUInt16(dataStage.Length),  ref  bytesReturned, IntPtr.Zero)))
                    return  false ;

                String str =  "sundyn" ;

                dataStage = System.Text.Encoding.Default.GetBytes(str);

                setupPacket.RequestType = 0X40;
                setupPacket.Request = 52;
                setupPacket.Index = 0;
                setupPacket.Length = Convert.ToUInt16(dataStage.Length);
                setupPacket.Value = 0;
                if (!(NativeMethods.WinUsb_ControlTransfer(winUsbHandle, setupPacket, dataStage, Convert.ToUInt16(dataStage.Length),  ref  bytesReturned, IntPtr.Zero)))
                    return  false ;

                setupPacket.Index = 1;
                if (!(NativeMethods.WinUsb_ControlTransfer(winUsbHandle, setupPacket, dataStage, Convert.ToUInt16(dataStage.Length),  ref  bytesReturned, IntPtr.Zero)))
                    return  false ;

                setupPacket.Index = 2;
                if (!(NativeMethods.WinUsb_ControlTransfer(winUsbHandle, setupPacket, dataStage, Convert.ToUInt16(dataStage.Length),  ref  bytesReturned, IntPtr.Zero)))
                    return  false ;

                setupPacket.Index = 3;
                if (!(NativeMethods.WinUsb_ControlTransfer(winUsbHandle, setupPacket, dataStage, Convert.ToUInt16(dataStage.Length),  ref  bytesReturned, IntPtr.Zero)))
                    return  false ;

                setupPacket.Index = 4;
                if (!(NativeMethods.WinUsb_ControlTransfer(winUsbHandle, setupPacket, dataStage, Convert.ToUInt16(dataStage.Length),  ref  bytesReturned, IntPtr.Zero)))
                    return  false ;

                setupPacket.Index = 5;
                if (!(NativeMethods.WinUsb_ControlTransfer(winUsbHandle, setupPacket, dataStage, Convert.ToUInt16(dataStage.Length),  ref  bytesReturned, IntPtr.Zero)))
                    return  false ;

                setupPacket.RequestType = 0X40;
                setupPacket.Request = 53;
                setupPacket.Index = 0;
                setupPacket.Length = 0;
                setupPacket.Value = 0;
                if (!(NativeMethods.WinUsb_ControlTransfer(winUsbHandle, setupPacket, dataStage, Convert.ToUInt16(dataStage.Length),  ref  bytesReturned, IntPtr.Zero)))
                    return  false ;

                return  true ;

            }
            catch  (AccessViolationException ex)
            {
                // The handle might be closed.

                return  false ;
            }
        }

3.修改Winusb 驱动 INF  文件适应Android设备，主要是GUID和PID、VID

4.Android USB 口强制安装修改过的驱动

OK ... 通信成功
