InputReport是什么东西?是报告描述符吗?

Result = ReadFile \\
(ReadHandle, \\
InputReport, \\
Capabilities.InputReportByteLength, \\
&BytesRead, \\
NULL);




ActualBytesRead = BytesRead;

if (Result == 0)
{
//The ReadFile failed, so close the handle, display a message,
//and set DeviceDetected to FALSE so the next attempt will look for the device.
CloseHandle(ReadHandle);
DisplayData(\"Can\'t read from device\");
DeviceDetected = FALSE;
}else{
  DisplayData(\"ReadFile 成功!\");
ULONG aa;
for(aa=0;aa<Capabilities.InputReportByteLength;aa++){//Capabilities.InputReportByteLength==4
    char x=InputReport[aa] ;
CString ms;
ms.Format(\"%08X\",x);
DisplayData( ms );
}

是输入报告啊 ！！~~

自定义的存储区，用来存储从设备读到的数据的

你的程序可不可以传上来看看，我也有个类似的，但是调试的时候总是通不过
