请教如何实现控制传输！！！！！！！！！！！

如果我要通过ep0给外设传送指令数据（0x80），该如何实现呢？

看来还是要等斑竹来解决问题了，难道你们做的项目不用ep0传输命令吗？

你是做usb boot吗？能不能说详细点？   [/我是菜鸟]

我做的是USB采集，需要给外设发送指令，因此用到EP0

端口0发送vendor命令如下，driverstudio程序：

NTSTATUS Mp3testADevice::MP3TESTA_IOCTL_800_Handler(KIrp I)
{
NTSTATUS status = STATUS_SUCCESS;
//#######################
// int iTest;
UCHAR cBufferA;
UCHAR cBufferB;
UCHAR *pBuffer;

pBuffer=(PUCHAR)(I.IoctlBuffer());

// cBuffer=*(PUCHAR)(I.IoctlBuffer());

cBufferA=*pBuffer;
pBuffer++;
cBufferB=*pBuffer;

ULONG dwInputBufferSize = I.IoctlInputBufferSize();
ULONG dwOutputBufferSize = I.IoctlOutputBufferSize();

//########################

t << \"Entering Mp3testADevice::MP3TESTA_IOCTL_800_Handler, \" << I << EOL;

//###########################

t << \"xxxxx:MP3TESTA_IOCTL_800_Handler, the receive data A: \" << cBufferA << EOL;
t << \"xxxxx:MP3TESTA_IOCTL_800_Handler, the receive data B: \" << cBufferB << EOL;

t << \"xxxxx:MP3TESTA_IOCTL_800_Handler, the receive data length \" << dwInputBufferSize << EOL;
t << \"xxxxx:MP3TESTA_IOCTL_800_Handler, the need to send data length \" << dwOutputBufferSize << EOL;

//###########################

// TODO: Verify that the input parameters are correct
// If not, return STATUS_INVALID_PARAMETER

// TODO: Handle the the MP3TESTA_IOCTL_800 request, or
// defer the processing of the IRP (i.e. by queuing) and set
// status to STATUS_PENDING.

// TODO: Assuming that the request was handled here. Set I.Information
// to indicate how much data to copy back to the user.

//###########################

PURB pUrb;

UCHAR buffer[8];
memset(buffer,0,8);

buffer[0]=cBufferA;
buffer[1]=cBufferB;
buffer[2]=3;
buffer[3]=4;
buffer[4]=5;
buffer[5]=6;

/*

{

}
else
{
//submit the URB to USBD
status=m_Lower.SubmitUrb(pUrb);

t << \"xxxxx:MP3TESTA_IOCTL_800_Handler, submit the URB and the status is \" << status << EOL;
t << \"xxxxx:MP3TESTA_IOCTL_800_Handler, the max LUN is \" << buffer[0] << EOL;

delete pUrb;
}

谢谢，其实我说的主要是固件侧该如何动作。

从端点0out来了个数据包，判断数据包是不是setup包，是，去执行setup包的函数。
不是，判断有没有数据，有读进来，没有返回ack。

嘿嘿，好象是，不太记得了。
 :D

有这样的例子吗？通过ep0写一个值给外设的例子

斑竹来看看我的问题吧，我这个问题一直不知道如何解决啊，我提出来几天了，但是一直没有解决，希望提供帮助
