Não consigo encontrar nenhuma alteração no meu /dev
removendo o dispositivo USB.
Parece que você tem o que é conhecido como Soft Modem (às vezes chamado de WinModems).
Esses dispositivos não se apresentam como um modem normal (como um dispositivo serial que aceita comandos AT), mas como um dispositivo USB personalizado que requer um driver especial. Esses drivers eram tradicionalmente disponibilizados apenas para Windows e, como tal, eram inutilizáveis por qualquer outro sistema operacional.
Uma pesquisa rápida gerou esta página do Ubuntu que pode ajudar, pois fala sobre um módulo de kernel personalizado que pode funcionar com o seu dispositivo. Mas a página faz referência a kernels 2.6.x, então pode estar MUITO desatualizada.
Você também pode dar uma olhada no linmodems.org , que costumava abrigar o trabalho da comunidade para tentar tornar esses dispositivos úteis no Linux.
ps a resposta mais curta e fácil aqui, pode ser sair e comprar um modem REAL
