Je travaille sur la création d'un périphérique HID virtuel dans Windows 10. J'essaie d'utiliser le Windows Virtual HID Framework (comme décrit ici: https://msdn.microsoft.com/en-us/library/windows/hardware/dn925056(v=vs.85).aspx) pour générer le pilote. Au stade actuel, je travaille juste sur l'installation correcte du pilote sur une machine virtuelle Windows 10. Mon code pilote est la suivante:Windows Virtual HID Framework Méthode VhfCreate retournant STATUS_INVALID_DEVICE_REQUEST

J'ai suivi le guide que je lié à mieux que je pouvais, mais l'appel à VhfCreate renvoie STATUS_INVALID_DEVICE_REQUEST. Je me demande ce qui conduirait VhfCreate à retourner cette erreur, et comment y remédier.
pendant un certain temps que je sorte de cette question négligé, mais ce que je fini par avoir à faire. Merci! – bacowan
