I'm on Ubuntu 10.04 and I have the same problem .. Since I did a "Safely remove" on my internal card reader it stopped working .. even after rebooting.
Then I started using my external USB card reader since I needed to keep working, and after a while I always ended up clicking "Safely remove" .. a bad Windows habit that sticks..
So one by one I killed my all my ports, now my card reader wont work in ANY USB ports and rebooting does not resolve the issue at all.

This situation is ridiculous, really.
