Assistance required with USB driver for video capture device

We are current attempting to use a Sensoray 2251 USB video capture device in Windows Standard 7 Embedded. The drivers supplied work with Windows 7 but do not work correctly in the embedded environment. (even a full build) We suspect that this is due to some missing system component or codec in the embedded build. **The task is to investigate this issue and provide definitive guidance as how to overcome the problem. i.e. what do we need to do to make these drivers work with Windows Standard 7 Embedded.** A link to the drivers and SDK is below: <[login to view URL]>
