BT4 and rausb0 (the driver I used in BT3)

After much trial, I finally figured out how to configure my USB wireless adapter that utilized the rausb0 driver in BackTrack 3. Since moving over to BackTrack 4 I haven't been able to use my external USB adapter.

Below is the command I was using with the resulting error:

root@bt:~# ifconfig rausb0 up
rausb0: ERROR while getting interface flags: No such device

I finally figured out that they have updated the driver for my Hawking device to use the wlan0 driver instead. I'm not sure how this works for other devices but it fixed my problem. New command:

root@bt:~# ifconfig wlan0 up
root@bt:~#

Success!
