Hi RobSinc,
Thank you for posting your question on Windows Vista Forums.
I will recommend you to download and install drivers from the given link for Eye-One Display2 calibration device:

However, if you still can’t use the device, I will recommend you to contact the device manufacturer and they should be able to provide you further information.
You can contact the device manufacturer by using the following link:

Also, if you can verify that there are no yellow exclamation or red cross mark in the device manager for the device, we may have to uninstall the hardware completely and then reinstall it back on the machine.
Hope the above information helps. Please post back and let us know.
Regards,
Ashish Gupta – Microsoft Support
