AFAIK this device use the bcm43xx chipset from broadcom....
wich is fully supported and natively installed on BT
im sure of this fact.....i check on specification list........
802.11g F5D7051 man: 050d dev: 7051 USB Broadcom Bcm43xx
that means you don't need to use ndiswrapper or any ralink driver(rt2570)
please remove ndiswrapper module from memory
plug your adapter
modprobe bcm43xx
ifconfig -a
you will see your adapter as ethX
hope it helps
