OK, got KK and tried out the Meenova card reader and it doesn't work stock as many of you already noted. So I downloaded Nexus Media Importer and gave it a go. Seems to work just fine. The only issue I am seeing is that you have to use their interface to read the card data, and for some files not all programs are shown (like an mpeg video file doesn't show mvideo player as an app that can play it, but with an mp4 it does). And as far as music, there is a built in music player, so no go if you want to use an app like Poweramp for playback. I don't know if other card reading apps would work better, or if the Dev for NMI will allow for more flexibility in future updates, but for now this allows for reading and writing to your Meenova card reader.
