Dissecting keyboard and CCID from usbmon

I'm looking for a protocol dissector for usbmon that would give human readable output of "key X pressed", "key X released" when capturing a standard USB keyboard. I hope something like that would already exist.

As a bonus I'd also like to dissect CCID frames from usbmon which probably does not yet exist and I would need to develop a custom dissector (to confirm that a smart card reader in fact is insecure in all conditions). I've skimmed through the README.developer file and will google/read more but any pointers to easy start would be most appreciated.
