    Default problem with Edimax ew-7318usg in Backtrack

    Hello!
    I just purchased Edimax ew-7318usg USB WiFi adapter, but I can't get it to work in Barcktrack. I've read every post here and did everything necessary, but it sill doesn't work.
    First maybe I should tell you that when I type lsusb command - the USB is shown as:
    Code:
    Bus 008 Device 002: ID 7392:7318
    not
    Code:
    Bus 001 Device 002: ID 148f:2573 Ralink Technology, Corp. RT2501USB Wireless Adapter
    I have tried every method that I could find here to troubleshoot this:
    1.download the kernel source from offensive-security.com/modules/kernel.lzm
    go where you downloaded the source and type:
    Code:
    bt tmp # lzm2dir kernel.lzm /
    then go to rt73 [Aircrack-ng] and follow the instructions from there(downloading, compiling and loading driver module) or follow this quick steps:
    Code:
    wget homepages.tu-darmstadt.de/~p_larbig/wlan/rt73-k2wrlz-3.0.3.tar.bz2
    tar -xjf rt73-k2wrlz-3.0.3.tar.bz2
    cd rt73-k2wrlz-3.0.3/Module
    make
    make install
    modprobe rt73
    Still no luck with this one!

    2. Then I've tried this:
    Code:
    After several failed attempts to get my Edimax EW-7318USg wireless USB adapter recognized in Linux using the RT73 enhanced drivers (3.0.3), I finally realized the USB device ID was not listed where it should have been in the file rtmp_def.h with the rest of the RT73-based devices. Edimax must have changed the ID fairly recently because I was hardly able to find anyone who reported having trouble with this device aside from one particular forum topic which was of little help.
    
    After updating rtmp_def.h and recompiling the driver, the device was then recognized as expected.  If you are experiencing a similar problem with this adapter, try the following:
    
    Disconnect the adapter and remove the existing kernel module:
    
    modprobe -r rt73
    
    Add the new device ID to the bottom of rtmp_def.h in the VID/PID area:
    
    /* Edimax EW-7318USg */\
    {USB_DEVICE(0x7392,0x7318)},\
    
    Recompile and install the driver (as root):
    
    make && make install
    
    Add the module back:
    
    modprobe rt73
    
    After reconnecting the device, the dmesg command should now show the device as being registered by the RT73 driver. Note that this was after blacklisting the rt73usb and rt2570 drivers.
    Again no luck!

    Is there anybody who fixed this problem and can make step-by-step, because I am going crazy with this USB. I just bought it and it is irretating that I cannot get it to work.
    Please Help!
    Thanks in advance!

    First, thanks for researching & trying so solve the problem by yourself instead of asking question. We really really appreciate this kind of behaviour.

    Well, I had the same device & it worked perfectly. The only step I did differently was, instead of using the current version:

    cd rt73-k2wrlz-3.0.3/Module
    make
    make install
    modprobe rt73[/CODE]
    I used the older one. I can't remember which version but you can try 3.0.2.
    Good luck!

    Code:
    wget homepages.tu-darmstadt.de/~p_larbig/wlan/rt73-k2wrlz-3.0.2.tar.bz2
    And, this guy was happy with the solution.
