The missing SMD is a ceramic capacitor. Unfortunately, SMD components like that are nearly never properly labelled.
What you can do is remove the one next to it, test the capacitance, and try to find a duplicate that's the same size with the same capacitance. You'll need either hot tweezers or a hot air gun to remove and replace SMD's like that.
You could also just solder a wire across the pads, and there's a good chance the card would work.
