GL823 side components

[remopong]

Hi, I'm currently working on a big project and I'm trying to use the GL823 CARD READER chip. I wired everything as it should be but my problem is that even if the card reader is detected, the micro sd soldered to it, isn't... I saw somewhere I should maybe place some capacitors, from VCC to VSS but, what capacity and where could I find a document that tells me how to make it work ? Thanks
