Thank you for replying. They both came with the lexar reader (this one in fact: http://www.amazon.com/Lexar-High-Speed-MicroSDHC-Memory-LSDMI32GBSBNAR/dp/B004AM610M).
When I tried swapping the readers with the cards, the results would be mixed, sometimes the same disconnecting, or not being recognized at all. I'm suspecting a driver issue but it's odd that would be for two different computers that I maintain and keep up to date. I did try another reader that was from kingston, but it wouldn't read them either. And it does read other microsd cards I can verify.
