I have nto tested this ont eh sharp rom but this is what I would think you need to do:
usbctl on 1
modprobe p80211
modprobe prism2_usb
source /etc/wlan/shared
wlan_bring_it_up
I have OpenZaurus on my 6000 right now so Ic an not test that and see if that is correct but if I remember right that is the proccess needed. You will also need to edit /etc/wlan/wlan.conf to point to the correct /etc/wlan/wlancfg-SSID files so that it knows how to connect.
