Hub USB agindo de forma estranha no Ubuntu 12.04 LTS.
No Windows, todos os dispositivos estão funcionando corretamente, mas no Ubuntu há vários problemas, por isso não é problema de hardware.
-
O disco rígido não é reconhecido, a menos que seja o único dispositivo conectado ao hub. Caso contrário, desliga-se após 1 segundo, reinicia, desliga - loop infinito.
-
Adicionar e remover o modem reinicia os demais dispositivos.
-
Quando qualquer um dos dispositivos está funcionando com desempenho total, o sinal do mouse se torna realmente uma semana e às vezes fica atrasado.
Que tipo de daemon possui meu Ubuntu 12.04?
ATUALIZAÇÃO:
Link para o modelo Trust HUB USB
Esquema:
Laptop Samsung
< - fio USB2
< - HUB USB
< - Telefone, HDD, modem 4G, receptor de mouse.
