Olá pessoal. Tudo bem? Sou iniciante em linux, to tentando aprender essa bagaça, mas tem uma panezinha que tá me tirando do sério.

Tenho um Raspberry Pi2 rodando 2 sistemas de aviação. Um é para receber e decodificar sinais ADSB e o outro é para receber e fazer streaming da comunicação dos pilotos com os órgãos de controle (isso não é ilegal, antes que perguntem! rsrs).

Os dispositivos USB que uso são estes:
ModeS Beast (compatível FTDI), que recebe dados ADSB
Dongle com chipset RTL2832, que "ouve" o rádio dos pilotos.

Estes 2 dispositivos entram em conflito quando reinicio o RPi. Aí nenhum dos 2 funciona.

Pra vcs entenderem melhor o que acontece, aí vão 2 logs do dmesg:

Esse é quando inicio o RPi com ambos os dispositivos conectados via USB:

Esse aqui é quando inicio o RPi sem o RTL e plugo ele DEPOIS do boot, aí tudo funciona normalmente:
