외부 WiFi 카드가 있는 Raspberry Pi 3의 Hostapd

Hostapd 및 dsnmasq와 함께 외부 USB WiFi 카드를 사용하여 Raspberry Pi 3에 AP를 설정하려고 합니다. 내부 WiFi 카드를 사용하여 이 작업을 성공적으로 수행했지만 외부 WiFi 카드로 전환하려고 하면 다음 오류가 발생합니다.

$ sudo /usr/sbin/hostapd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
nl80211: Could not configure driver mode

nl80211 driver initialization failed.
wlan1: interface state UNINITIALIZED->DISABLED
wlan1: AP-DISABLED 
hostapd_free_hapd_data: Interface wlan1 wasn't started

나는 이것이 Hostapd가 기본적으로 nl80211드라이버를 사용하기 때문이라고 생각합니다. lsusb- 의 출력 입니다 Bus 001 Device 004: ID 148f:3072 Ralink Technology, Corp. RT3072 Wireless Adapter. 이것은의 출력입니다lshw

분명히 이 카드는 rt2080usb드라이버를 사용하고 있지만 드라이버를 넣고 hostapd.conf수동으로 부팅하려고 하면 hostapd다음 오류가 발생합니다.

$ sudo /usr/sbin/hostapd /etc/hostapd/hostapd.conf

이것은 내 hostapd.conf파일입니다:

[편집] 이것은 명령의 출력입니다 iwconfig.

다음은 명령의 출력입니다 iw list.
