寫入USB HID設備

寫入HID設備時出現問題; 下面是用史努比製作的兩個日誌。第一個是使用設備製造商的原始演示SW製作的，第二個是我的SW日誌。我的軟件不支持此設備，但可與另一個HID設備一起使用。寫入USB HID設備

原始軟件：

No TransferBuffer

代碼用於發送數據看起來是這樣的：

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是正確的，變量「b」被執行後爲真。

任何想法？

我在做什麼錯了？

原文：

Function: 0009 (BULK_OR_INTERRUPT_TRANSFER)

你的程序：

Function: 0008 (CONTROL_TRANSFER)

HID規範允許兩個IIRC，但似乎你的硬件是挑剔，只使用中斷端點時工作。
