This is a AR5008 device, which is not supported by MadWifi 0.9.4.
You'll need a snapshot from the Subversion repository to support it.
Snapshots from the trunk should be OK for that device:

Because the driver doesn't support the device.

You are using MadWifi.

> 3.  If it's madwifi will it work with an 802.11n card such as the DWA-645?

Future releases of MadWifi will work with the card, but 802.11n
functionality is not planned.  If you need 802.11n support, use ath9k.
You'll need a recent Linux 2.6.27 release candidate for ath9k.
