[SOLVED] ath9k_htc not loading

Question

I just built a needed wireless driver (ath9k_htc) from AUR.  I thought that installing it from pacman would place it in the correct location for loading, but after reboot, 'lspci -k' showed the module hadn't been loaded, even though I'd set up a config in /etc/modules-load.d/ to do so. Here's some output from the build http://bpaste.net/show/N2Yl4UPewiLOupTfuYS1/
I'd appreciate any advice to move the needed file to the correct location (if necessary) and what I may have overlooked to get this module loaded at boot.
Reference: backports-patched 3.11_rc3_1-6

First, this driver is in the kernel already, so no need to compile form AUR, especially when what you compiled is older than the current kernel. Second, ath9k_htc is an USB driver, so of course it won't show up in lspci.
Which wireless card do you have? Once you know that (using lspci if it's an internal card, or lsusb if it's an external adapter), you can research which driver you need. Most are in the kernel already and require no special setup.
Yes, it's a Netgear N150 Wireless USB Adapter WNA1100 which requires the ath9k_htc driver and the htc_9271.fw firmware (which I have installed).  My understanding is that there's an ath9k driver already built-in as you say, but that the ath9k_htc driver is different and is meant to support my particular USB device and has to be installed via backports-patched (though, I could be mistaken about that).  I have very limited experience with networking issues (wireless, in particular), so it's easy for me to overlook something.  However, the reason I made the distinction is because that particular module (ath9k_htc) is mentioned on the wiki as needing to be built via the backports-patched package in AUR.
Right now, the module lives at /usr/lib/modules/extramodules-3.12-ARCH/drivers/net/wireless/ath/ath9k/ath9k_htc.ko.gz
...and I tried loading it in /etc/modules-load.d/netgear_wna1100.conf both with the line "ath9k_htc.ko.gz" and "ath9k_htc" but it didn't seem to work, though as you pointed out, I checked with 'lspci -k' and not 'lsusb -v' which I'll do now after a reboot (I'm on an XP partition at the moment, which has net access) and then I'll update this post with the results.

Here is the output of lsusb -v:

There doesn't seem to be any driver information, but I guess it might be safe to assume the correct one has been loaded by virtue of the fact that lsusb showed this info?
