Hostapd가 내 장치 중 하나에서 작동하지 않습니다

WiFi 어댑터를 사용하여 Raspberry Pi Compute Module 3+를 액세스 포인트로 설정하려고 합니다.

나는 이 튜토리얼을 따르고 있습니다:https://elinux.org/RPI-wireless-hotspot.

동글 EP-N8508GS를 사용하여 액세스 포인트를 설정할 수 있지만 TL-WN722N을 사용하려고 하면 다음 오류가 발생합니다.

pi@raspberrypi:~ $ sudo service hostapd start
Job for hostapd.service failed because the control process exited with error code.
See "systemctl status hostapd.service" and "journalctl -xe" for details.

이는 nl80211 드라이버의 문제인 것 같습니다. 그런데 왜 첫 번째 동글에서는 작동하고 다른 동글에서는 작동하지 않는지 잘 모르겠습니다. 첫 번째 동글은 AP 모드를 지원하지 않고 장치가 연결을 시도할 때 커널이 충돌하기 때문에 tp-link 동글을 사용해 보고 싶습니다.
