2. Q: For CF and SD card (or MicroSD)  it can't read at the same time. When the second card is plugged in, the first card can not work. Is it correct? 
- A: Yes, it can not read two cards or more at the same time.
3. Q: I tried an 8GB, 32GB microSD card but it couldn't be identified. But I put the microSD card into the microSD card adapter, then insert it into the product, then it could read the card, why?
- A: First, you can try to change another card or re-pull out the microSD card and insert the card reader again. The second reason is that related to the data cable. Or the card maybe plug in the opposite direction.
