WinUSB – Wie empfange ich isochrone Daten vom USB 2.0 High Speed ​​IN-Endpoint von der Capture Card? [geschlossen] ⇐ C++

[Guest]

Ich erhalte die Fehlermeldung, dass ich isochrone Daten von einem USB-Gerät empfange, bei dem es sich um eine Capture-Karte handelt. Bitte raten Sie mir nicht, UVC-Treiber zu verwenden, es sei denn, WinUSB kann die Aufgabe nicht ausführen.
Hier ist der Fehler: Ich kann nicht herausfinden, welcher „Parameter für WinUsb_ReadIsochPipe falsch ist“< /code> um eine Anfrage zum Empfang von Daten ordnungsgemäß auszuführen.
