写入USB HID设备

写入HID设备时出现问题; 下面是用史努比制作的两个日志。第一个是使用设备制造商的原始演示SW制作的，第二个是我的SW日志。我的软件不支持此设备，但可与另一个HID设备一起使用。写入USB HID设备

原始软件：

No TransferBuffer

代码用于发送数据看起来是这样的：

hiddata.ReportID := 0; 
hiddata.Data[0] := 6; 
hiddata.Data[1] := $16; 
hiddata.Data[2] := $19; 
hiddata.Data[3] := $17; 
for I := 4 to 64 do 
    hiddata.Data[I] := $0; 
b := HidD_SetOutputReport(HidHandle, @hiddata, 65);

HidHandle是正确的，变量 “b” 被执行后为真。

任何想法？

我在做什么错了？

原文：

Function: 0009 (BULK_OR_INTERRUPT_TRANSFER)

你的程序：

Function: 0008 (CONTROL_TRANSFER)

HID规范允许两个IIRC，但似乎你的硬件是挑剔，只使用中断端点时工作。
