Archlinux의 Broadcom 43142: 인터페이스 없음

BCM43142용 드라이버가 내 노트북에 설치된 것 같습니다.

lspci -k
02:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)
        Subsystem: Dell Wireless 1704 802.11n + BT 4.0
        Kernel driver in use: bcma-pci-bridge
        kernel modules: bcma

그러나 장치와 연결된 무선 인터페이스가 없는 것 같습니다.

ip link

무선 장치에 대한 정보가 출력되지 않습니다. Archlinux 문서를 확인했는데 인터페이스(예: wlan0)를 무선 장치에 연결하는 방법이 설명되어 있지 않습니다. 이 문제를 어떻게 해결할 수 있을지 아시나요?

dmesg| grep bcma

고쳐 쓰다dmesg:다음과 같은 결과가 나타납니다.
