hy guys.

I'm using bt4 pre final and have a device which came with the chipset ralinktech 3070.
when I plug in the hardware and want to set it up to the monitor mode it looks like this.

root@bt:~# airmon-ng start ra0
Interface Chipset Driver

ra0 Ralink 2560 PCI rt2500 (monitor mode enabled)
I can't understand why there stands PCI where the device is an usb adapter.

iwconfig looks like this
root@bt:~# iwconfig ra0
ra0 RT2870 Wireless ESSID:"" Nickname:"RT2870STA"
Mode:Auto Frequency=2.412 GHz Bit Rate=1 Mb/s
RTS thr:off Fragment thr:off
Encryption key:off
Link Quality=10/100 Signal level:0 dBm Noise level:-95 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
As you can see there stands rt2870 and in the airmo-ng rt2500. But the device has the chipset rt3070.

After setting the device in monitor mode, it can't find any networks in range. Neither with airodump-ng ra0 nor with Wicd Network Manager.

So, what is the problem? Does backtrack4 pre final not support rt3070?
And how can we understand why there stands different chipset names in iwconfig and airmon-ng?

haven't installed any additional driver or changed anything in the system.

thanks for the answer
