Have you tried inserting the card in the reader, then plugging the
reader into the usb port? That is, if it's an external reader. Have
you cleaned the contacts?
Your card could have a error (or errors) on the filesystem that might
prevent it from being mounted, while still being recognized. Had it
happen. Two days ago, in fact. Running dosfsck and reformatting solved
the problem.
At worse, you could write a udev rule to mount that specific card.
