The default device is not "hw:0,0" but "default" which gets eventually
mapped to "plug:hw:0,0".

The subdevice number would be the third number (as in hw:0,0,0).
The first device on your first card has exactly one subdevice which has
exactly two channels.
A card has more than one device if it has several output/inputs that can
be used _independently_ (i.e., if the hardware can play from different
streams). For example, the analog and SPDIF outputs of Intel compatible
AC'97 controllers are available as hw:0,0 and hw:0,4.
A device has more than one subdevice if the hardware can mix several
streams for the same output.

Hope this helps.
