The serial number for Osprey cards is an 8-digit number preceded by the letters “MM”. The serial number is located on a sticker placed somewhere on the card itself.

You can also find the Osprey card serial number from a running application via the driver property pages. To do this, go to the Osprey driver properties page (for example, when using the OspreyConfig utility, double-click the device's Video Filter). Change to the “Device” tab, and hit the “Device Info” button. The serial number is displayed on this window without the “MM”.
