I have a Dell TrueMobile 1300 USB WLAN Card and I would like to use it on BackTrack 4 since my desktop does not have an integrated WLAN card. I have tried to start up the card using the "ifconfig wlan0 up" command but no luck, and I have also tried using the "/etc/inti.d/networking start" but that did not work either. Is there anyway I can enable BackTrack 4 to pick up USB devices or in this case the wireless card?
