Estou executando o Xubuntu 12.04 em um laptop Asus X83V e alguns dias atrás, todas as minhas portas USB pararam de responder, sem que meu mouse nem flash drives ou nenhum dispositivo usb estivesse respondendo. Quando conecto meu telefone a qualquer porta USB, ele é carregado, mas não se conecta ao meu laptop. O mesmo acontece com meu mouse, que acende mas não responde.
Minha saída lsusb com ou sem dispositivos conectados é:
~$ lsusb

Estou executando o kernel 3.2.0-34-generic e tentei atualizá-lo para 3.6, mas sem sucesso. SOS?
