I come here to share my experience with the best driver, in my opinion, for my Vengeance 2000 headset.
The driver name is Vengeance2000SW_1_7_051512
I have used this driver across Windows 7, 8, 8.1, 10 with this driver producing the best sound for my noggin'.
To get them to work on anything above 7 just right click the installation .exe and troubleshoot compatibility and it should work as normal.
If you are looking to download them you can visit my Dropbox here: click me I downloaded and save these from Corsair's download section for the Vengeance 2000's long ago.
