Hi, I am new to this forum and to linux, so if I post with bad etiquette or anything, I apologize.

Alright, here is my problem. I am running Backtrack 5 r3 fully installed on my hdd, with a TP-link TL-WN722N USB wireless card. I know that Backtrack detects my device because it shows up as 'Atheros AR9271' (I shortened that name a little but I will post the results of lsusb below which has the full name) when I run lsusb. However, when I open wicd, it shows that there are no networks available. Here are some ideas I've had:
1) I have the AR9271 driver, but I don't know if it's installed or not (it may be installed by default but I am not sure).
2) It may have something to do with me needing to do a modeswitch. I tried usb_modeswitch -v 0cf3 -p 9271 but didn't seem to have any luck with it (I will post the result of that below).
3) My wireless interface file seems to be lacking something, but I am not sure what (I will post its contents below), and if it is, I am not sure what to do with it.
4) The wireless card is a USB 2.0 device (as are my mouse and keyboard), and when I am on Windows the wireless card won't work in a USB 3.0 port. However, when I am on backtrack none of the USB 2.0 ports work; it doesn't recognize my mouse, keyboard, or wireless card unless they are plugged into one of the USB 3.0 ports. So I am thinking this whole thing could have something to do with the level of compatibility my wireless card has with USB 3.0. I know nothing about that, though.

Here are the results of a few commands:

lsmod

and finally the contents of my network interface file

Code:
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto wlan0
iface wlan0 inet dhcp

So that was probably a bit too much information, but I thought I'd err on the side of caution.
Thanks in advance to anyone who reads this, or to anyone who can help me!
