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
