Sennheiser PC 35 USB and Windows Vista Driver problem

I bought my Sennheiser PC 35 USB for its noise cancelling microphone. I was very excited to connect it to my Samsung Q35 notebook and make it run my voice commands.

Problem was that it wouldn’t install properly on my notebook. A visit to the Sennheiser product website at icm_eng.nsf/root/500910# wasnt of much use or help, as there was no driver in there as well.

I then fired an email to their support to ask for assistance. Anyone out there with the driver? Or is this a Microsoft Vista problem on the USB?
