Não ajuda não, nenhum dos problemas descritos no artigo está me afetando. Ainda assim, fiz os ajustes de configuração conforme recomenda o artigo.
Renato:
Vc já olhou se os módulos usb ehci_hcd e o ohci_hci estão carregados? Tente carregar o módulo usbserial tb...
# lsmod | grep ehci_hcd <-- pra v se o módulo ehci_hcd tá carregado
# modprobe usbserial <-- pra carregar o módulo 
[CUT]
Acabo de fazer essas verificações e percebi que:
root@ubuntu:~# lsmod | grep ehci_hcd # Comando sem saída, o módulo ehci_hcd não está carregado. Como devo carregá-lo?
root@ubuntu:~# modprobe usbserial # Executei esse comando ok e não deu em nada também.
Dando um tail -f /var/log/messages, obtenho o seguinte resultado:
