your mike shouldn't need a driver - it should 'just work' - it won't show up in device manager either - that's normal
maybe you actually need to 'turn it on' and turn up the recording level. it's a bit of a lengthy process, but you only need to do it once.
control panel >> hardware and sound >> sound >> recording tab
you should see an entry for a microphone here
click on it >> configure >> levels >> turn it right up and turn on boost if you have that option
good luck and please let us know if it works, or if you need more help
