Firewire card for PC, Pcie 1x interface (Stroud GL5)

Just bought an old scanner which has Firewire and USB 2.0 interfaces., The USB interface is a bit dodgy, it's a bit loose, and cuts out sometimes. The scanner however also has Firewire interfaces, so I would like to try that as a more reliable option. Does anybody have a Pcie 1X Firewire card that they no longer use ? I have shown the interface in the photo. Many thanks if you can help.
