Do they show up in Last Import?
If the photo is in Last Import, then the photo is in the Library somewhere, just not where you expect it to be. Usual causes: the date on your camera is wrong, and so the date on the photo is wrong, or the sorting of the Events has changed (View Menu -> Sort Events)
Oops. I should have said F550EXR. I'm just looking at which camera to buy so I can't test it yet
I found the page of supported RAW formats. However, since Fujifilm FinePix X100 is supported I thought that things might actually work even with F550EXR if the format is the same.
Supported RAW formats
Yes, that's what I was working from

The Raw from every model of camera is different. Note: that's every model not every brand. So, the NEF produced by a Nikon D40 is not the same as the NEF produced by a D60, the CR2 produced by a Canon 350 is not the same as the CR2 produced by a Canon 400.
Therefore the Raw for every camera model needs to be added individually.
