My USB mouse and keyboard hang intermittently. Very weird things happen, i.e. my mouse's red LED light begins to flicker in a very weird fashion, or my keyboard stops responding and my sound output is suddenly muted by itself (I don't even touch sound).
This was in the /var/log/messages regarding sound: wrapper-2.0: vfprintf %s NULL in "[xfce-mixer-plugin. c:374 xfce_mixer_plugin_set_property]: could not set sound-card to '%s', trying the default card instead" wrapper-2.0: vfprintf %s NULL in "%s: muted" Nothing else to show up in /var/log/messages. Is there a more detailed log? How do I gather info about this from the system?
