Hi All,

I remember now that this headset can also be used (using some tools from
toshiba) for speech recognization. Based on the toshiba windows tools,
the settings for this voice recognition mode and audio mode is different,
so there is a chance that this 2nd SEID is used for that purpose, using
a Toshiba specific codec.
