d-link dwl-g122 wireless USB -- help recognizing device

[Marc Rios]

Could someone please help me troubleshoot for this wireless card I
have? I am using an iBook dual USB running 5.10; I am trying to use a
D-link DWL-g122 USB wireless card on my computer. I have followed the
directions from this howto: HOWTO: RALink 2570 usb wireless driver
(http://ubuntuforums.org/showthread.php?t=106846)

It is not working and I am not receiving useful advice. Here are some
salient facts that might help someone discover what I am missing.


This is the dmesg of my system when I plug in the USB device:

    rtusb: probe of 2-1:1.0 failed with error -12
    [ 4590.856611] usbcore: registered new driver rtusb
    [ 5405.759475] usb 2-1: USB disconnect, address 3
    [ 5409.134325] usb 1-1: new full speed USB device using ohci_hcd
and address 2
    [ 5409.401584] Device Descriptor not matching
    [ 5409.401612] rtusb: probe of 1-1:1.0 failed with error -12

The rt2570.ko driver is located in these directories:

    /lib/modules/2.6.12/extra/rt2570.ko
    /lib/modules/2.6.12-10-powerpc/kernel/drivers/net/wireless/rt2570.ko
    /lib/modules/2.6.12-10-powerpc/drivers/rt2570.ko

These are the configuration files that have been modified to make this
driver run:
/etc/modutils/rt2570 exists and contains the single line "alias rausb0 rt2570".
/etc/modprobe.d/rt2570 exists and contains the single line "alias
rausb0 rt2570".
/etc/modules contains the line "rt2570", insuring that the module is
loaded on boot.

This is my wireless configuration file:

    auto lo
    iface lo inet loopback

    mapping hotplug
    script grep
    map eth0

    iface eth0 inet dhcp

    iface rausb0 inet dhcp
    wireless-essid "something"
    wireless-mode Managed
    auto rausb0

    auto eth0

When I try to load the rausb0 device, this is my error message:

    sit0: unknown hardware address type 776
    SIOCSIFADDR: No such device
    rausb0: ERROR while getting interface flags: No such device
    rausb0: ERROR while getting interface flags: No such device
    sit0: unknown hardware address type 776
    Bind socket to interface: No such device
    Failed to bring up rausb0.

These are all of the important facts that may have some bearing on the
source of this problem.

Any help will be appreciated.
