We will definitely change our scripts, and understand that the device path is a better methodology. I just thought that intuitively it makes sense for the built-in wifi adapter to be probed before anything plugged into USB.

I had a brief look at the /sys/ device path, and since wlanX is derived from phyX. There doesn't seem to be a reliable way to reference the internal wifi adapter without knowing this fact (ie. that it is phy1 as opposed to phy0 with the current probe ordering). I might just be missing something though...

You might be able to enumerate through finding "/sys/devices/platform/ar933x_wmac/ieee80211/phy*" but I figure what is needed is a reliable single path (name) that doesn't require any iteration/enumeration.
