I have a Plantronics DSP-500 USB headset and it works fine with Vista
Ultimate x64 RTM.

A couple of things for you to check:

(1) Go to device manager and under sound etc. devices, see if Vista
installed the "Plantronics Headset" driver (provided by Microsoft, it comes
with Vista).

(2) Also go to the Sounds applet in Control Panel and make sure the headset
is set as your default device (assuming this is what you want). I use
speakers by default but choose the headset specifically in VOIP program
(Skype, etc.) that allow overriding the Windows default.
