Whenever I try to put a micro-SD card into the slot on my Surface RT, the card does not show up at all. I don't even get an acknowledgement that some device was inserted (other than the usual sounds). When I look it up in Device Manager, it says that the device is not working properly. What is the problem?
Thanks @Karan for your help. I contacted Microsoft Support and thay had me run the hardware troubleshooter, which fixed the problem.
