What kind of usb card is it? You may want to google the specific card on linux and/or test other cards of different types. And do lsusb and see if you can find the reader model, the bugs are specific to the readers and MB makers may pick whatever they have used before or whatever is cheapest, so don't count on the reader being old or new.
