how you are getting wlan0 the card model is hawking HWUG1 with rt73 based chipset.it support both discovery and injection.just do
either connect USB card after properly booting up BT3
and use airodump rausb0
aireplay -9 rausb0
or
after booting BT3 and USB card is attached then
ifconfig rausb0 down
modprobe -r rt73
modprobe rt73
airodump rausb0
aireplay -9 rausb0
injection will work fine.
