You wouldn't have the /sys/module cfg80211 entries if it wasn't
present - ath9k_htc simply won't work without it. I'm guessing it's
built in.
I suspect it's something else.
Do other devices work on that USB port? What happens if you plug it in
after it's booted?
Also, you should be using the iw command ("iw dev wlan9 scan") not
iwlist. Make sure you have the "iw" package installed.
Finally, scanning doesn't always work first time (i.e. the device is
busy doing something else) and it doesn't work before you configure it
up ("ifconfig wlan9 up") so try it a couple of times before calling it
completely broken.
Thanks,
