I'm guessing it is trying to read the reader's file system so it can display it but it is having trouble doing it. Do you have a memory card in the reader? If so, try removing it and see if that makes a difference.
You say it mounts to the file system without a problem. If you browse the device can you see all files on it? If so, can you run a checkdisk on it using explorer.
