didnt work in 12.10, didnt work in 13.04, and still not working in my beta 13.10. my computer is an acer v5-171. sometimes it used to work if the sd card was already inserted on start up. but not its doesnt seem to work ever. in fact, since upgrading to 13.10, the computer doesnt even shut down if there is an sd card in the slot on shut down, it gives me some error till i remove the card, then it shuts down fine. is there any hope???
