I dont know whats the fuss about this device. Its clear it DOES NOT run out of the box in virtual environment and those who have problems in BT R1 just unplugged and plug it in, that does the trick for and about BT5 well just disable all the rt2800usb & sta drivers then enable just those that you need.At least this way i get networking and injection and sniffing work great!!!

Using Backtrack 5 R1(Hard disk boot)
