    Question WUSB54GSC : iwconfig empty !?

    Hello, I'm a newbee on backtrack and I have already a problem : I can't make this linksys WUSB54GSC work.
    I have read about this wireless adaptater everywhere in your wiki's and a lot on the forums but no one seems to have the same problem as I..

    Please note that I don't have usb 2.0 on this laptop and I use a PCMCIA card to have 4 usb 2.0 ports. Well, it doesn't work for any of them anyway(even for the 1.0 ones)

    Here are some commands I used to help me :
    # tail -f /var/log/messages
    ...
    (now I plug the usb dongue)
    kernel: usb 5-4: new full speed USB device using ehci_hcd and address 2
    kernel: usb 5-4: configuration #1 chosen from 1 choice
    kernel: usb 5-4: usbcore: registered new interface driver cdc_ether
    kernel: usb 5-4: bad CDC descriptors
    kernel: usb 5-4: usbcore: registered new interface driver rndis_host

    if I type ifconfig I get the lo interface only and if I type iwconfig I get lo and eth0 interfaces with "no wireless extensions".

    if I type :
    # lsmod
    Module Size Used by
    rndis_host 9216 0
    cdc_ether 8960 1 rndis_host
    usbnet 17928 2 rndis_host, cdc_ether
    ...


    now really I have no clue of what I should do to make things work..

    Maybe I'm just a morron

    Thanks for help

    Edit : Changed from WUSB54GC to WUSB54GSC -_-

    Try plugging it in and running...

    ifconfig rausb0 up

    I use the same card and haven't had a problem with it yet.

    "ifconfig -a" will show you all interfaces whether powered up or not.
    To bring your card up just type "ifconfig rausb0 up".
    To bring it into monitor mode, type: "iwconfig rausb0 mode monitor".

    thousand time I have replied for the same problem in forum.plug your USB NIC after properly booting BT3 then use
    lsmod
    if it shows rt73 modules then use
    iwconfig
    will show rausb0
    monitor using airodump-ng rausb0
    injection test using aireplay-ng -9 rausb0
    if it does not show rt73 chipset module in output then pretty sure its not got loaded.then use
    modprobe rt73
    iwconfig
    should show rausb0 with wireless extensions.
    dont say us that you have searched the forum.I only made above 20 posts regarding the same problem.

    Perhaps you should start to use this as your signature, as you are pretty much forced to post this advice on a daily basis anyway.

    ok, so
    I boot BT3, the cable USB is unpluged
    After startup, launch konsole and then plug the cable
    dmesg shows the same output that I put above
    lsmod don't show rt73 so : #modprobe rt73
    it seems ok, rt73 is in lsmod output
    BUT, iwconfig shows nothing and ifconfig -a gives only lo and eth0.
    So "ifconfig rausb up" surely would fail.


    And yes I read the forum and looked a bit everywhere on the web during at least 2 hours, I'm not exactly new to linux ..
    Thanks anyway for your answers

    So, any idea ?

    Ok, after I tried what will appear above, I wanted to try again and run modprobe before plugging my usb nic
    I took the logs

    here I did the same thing except
    - I plugged the usb NIC in my Trendnet 4xUSB2.0 PCMCIA card
    - I did the modprobe after I plugged the usb NIC
    here is what I get in dmesg :
    Code:
    bt ~ # dmesg
    usb 5-3: new high speed USB device using ehci_hcd and address 2
    usb 5-3: configuration #1 chosen from 1 choice

    rt73: init
    rt73 k2wrlz modification 3.0.0
    usbcore: registered new interface driver rt73
    lsmod, iwconfig and ifconfig are same as above


    Well I forgot lsusb but when I typed it yesterday, it seemed ok, it knew it was a linksys hardware and I didn't notice something special..

    I wanna say that the usb NIC works very well on all usb ports in windows xp.

    Hope it will help you ;-)

    damn true Tron.I am afraid one day this forum would become either Atheros/ath0 or RT73/rausb0 forum
    then we will be just wandering in between discovery and injection mode.

    Well, I AM a morron

    My usb NIC is in fact WUSB54GSC Linksys Compact Wireless-G USB Network Adapter with SpeedBooster and not WUSB54GC..
    Should have done my homework right.

    Sorry for the mistake..

    Is it the same chipset/driver ?

    I bet I just bought THE one I shouldn't..

    don't worry guys, if that happens than I suppose you're gonna get "Senior Teacher" status, and I'm gonna be here to vouch for the legitimacy of the information you supply
