the module rt2860 does not exist within bt3 , so i don't know if your card will work.
What you can try is:
open the console and type "ifconfig -a"
Is there any rausb0 device? (can be different) If not try "modprobe rt73" and again "ifconfig -a".
Then you can do "ifconfig rausb0 up" and your card should work.
