knoppix wlan problem

[baxs]

I have a problem to get my prism3 usb wlan stick working.
dmesg says me:
usb.c:usb device 2 (vend/prod 0x124a/0x168b) is not claimed by any active driver.
I can not edit the /etc/module.conf there is
alias wlan0 prism2_pci
# alias wlan0 prism2_usb
so wen I give modprobe prism2_usb prism2_doreset=1
but the Linux is loading prism2_pci module.
And my script is not working
sh wlan.sh
#!/bin/sh


rmmod prism2_usb
sleep 1
modprobe prism2_usb prism2_doreset=1
wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
sleep 2
wlanctl-ng wlan0 lnxreq_autojoin ssid="default" authtype="opensystem"
sleep 3
ifconfig wlan0 192.168.0.16
route add default gw 192.168.0.1

Output is wlan-ng no wlan0 device wile the module prism2_usb is not loaded .....
Can somebody help me


Thanks
