Question

Eu tenho problemas com portas USB no laptop MSI WIND.

Eu tenho o FC17 instalado e a impressora USB às vezes não responde. Se eu reconectar uma impressora na porta USB - está funcionando. Tentei mudar o cabo USB e impressora também, não importa. Tentei outra distribuição Linux - não ajudou. Tentei usar outras portas USB no laptop - mesmo erro.

quando a impressora não está funcionando, há alguns erros em / var / log / messages:
