[C＃，HID]如何使用USBHIDDRIVER.dll在HID连接中写入数据

public void sendStartCMD()
        {
            byte[] startCMD = new byte[8];
            //Start
            startCMD[0] = 255;
            //Mode
            startCMD[1] = 0;
            //USync
            startCMD[2] = 28;
            //ULine
            startCMD[3] = 20;
            //tSync
            startCMD[4] = 20;
            //tRepeat - High
            startCMD[5] = 0;
            //tRepeat - Low
            startCMD[6] = 0x01;
            //BusMode
            startCMD[7] = 0xF4;
            //send the command
            
            usbI.Connect();
            usbI.write(startCMD);
        }

您好，我是C＃和HID USB通讯的新手。

我是发送数据时遇到问题。

我正在尝试使用USBHIDDRIVER.dll。我检查好了接收数据。

但是，当我尝试使用上面的函数发送数据时，usbI.write（）函数总是返回false。

当我用Beagle检查时，没有数据输出。



以及当我检查下面的函数时，NumberOfBytesWritten有0函数执行后。

Hi, I am new to C# and HID USB communication.
I am having trouble with sending data.
I am trying with USBHIDDRIVER.dll. and I checked receiving data well.
However, When I try sending data with the function above, usbI.write()function always returns false.
When I checked with Beagle, there is no data out.

and also when I checked the function below, "NumberOfBytesWritten" has 0 after the function excuted.

Result = USBSharp.WriteFile(hidHandle, ref outputReportBuffer[0], outputReportBuffer.Length, ref NumberOfBytesWritten, 0);

如何正确发送数据？如果有遗漏的话请告诉我。



非常感谢，

How can I send data properly? Please let me know if there is something I am missing.

Thank you very much,
