There are no GSA sentences in your sample log and i think gpsdrive
heavily relies on them to determine whether it knows the altitude or
not.
According to the manual of the 60CSx the device should use GSA. 
Did you set the Serial Data Format in the Interface Setup menu to NMEA
and if not, can you please verify if the problem persists with this
setting?

Thanks,
