Le hotspot WiFi ne fonctionne pas sur debian

J'ai un nettop ASUS avec un adaptateur WiFi et je veux l'utiliser comme hotspot.

L'adaptateur semble avoir été chargé avec succès, mais je ne peux pas le voir parmi les hotspots wifi à partir de mon téléphone portable Android.

J'ai configuré hostapd comme décrit ici mais sans connexion pontée car je n'en ai pas besoin pour l'instant.

Quelle pourrait être la raison pour laquelle mon hotspot ne peut pas être découvert ?

UPD : J'ai listé les erreurs hostapd au démarrage, mais je ne sais toujours pas ce que cela signifie, quel est exactement le problème avec le driver :
