I ran into the same problem with a BBB I recently purchased. Apparently the force from the sd contacts can lift the leads off the board after sitting for a few months. I re-soldered the socket leads on the side along with the grounds but still had a reliability problem with the card detect line. The demo software would boot from the sd but later not recognize the card. After several days of debugging the software, I finally traced it down to the sd socket lead on the end of the connector also disconnected. The card detect lead location isn't as obvious as the 4 side leads, it doesn't stick out so it can be challenging to re-solder. I thought I would pass this along if others are struggling with similar SD card detect issues.
