That driver would likely come from the board manufacturer's website, So.....
With a board Manufacturer Name, Model Number, Rev. Number and any other identifying numbers we might be able to help you with that, Or...
Open device manager, select then right click the problem device and choose properties, select the "Details" tab, use the drop down to change from Device description to Hardware IDs.
Right click in the "Value" box and choose Select all and then right click again and choose copy. Paste that information into your next post and we'll see if we can help track that information down.
