Identità della macchina[modifica]

L'identità di una macchina è un bel problema. Ho trovato questo sito in cui se ne parla in modo preciso, nel senso che intendevo io. Ho eseguito qui la traduzione.

Principalmente l'hardware di questo pc:

   marcob@jsbach:~$ uname -a
   Linux jsbach 3.2.0-37-generic #58-Ubuntu SMP Thu Jan 24 15:28:10 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Non va il mouse, ad un certo punto si blocca e non risponde più. A volte sconnettendo e riconnettendo l'antennina USB riprende a funzionare. Ora non più, solo con l'altra porta USB:

Sul web c'è questa discussione vecchia di un anno. Ma sembra molto legata alla mia.

L'elenco delle porte usb è questo:
