Logitech USB Mic/Headset not working with Vista. My Logitech USB mic/headset wont work with Vista

Question

My Logitech USB mic/headset wont work with Vista yet works on my Windows XP machine. Have done Windows update and so all my drivers are up to date according to MS. What else can I do. I dont have any Vista installation disk, my PC came with it already installed. There's a yellow ! listed next to the name in Device manager.
