If it cannot even enumerate then it must either be faulty hardware or a power issue...

Do you have an older version of the board or the new 512M version?

Have you tried using a powered hub?

Does your network interface work correctly?

you are going to need a powered hub for any wireless adapter [IME]
the basic RPi will not be able to provide enough power .
