Hi, Do you have experience of 3rd party SD-card readers? I bought bunch of these readers and none of them seem to work. I have checked the continuity from the card reader pins to the motherboard and all of them seems to be okay. However, the switch does not recognize the SD card. I have one original SD card reader which has no damage on the outside (and the connector looks fine) but there is no continuity from pin 8 or pin 9 (the pins on the right end) to the motherboard. The switch recognizes the SD card though.
There is a possibility that the problem is in the female connector on the motherboard. It was missing few pins and I (most likely) successfully soldered new ones. The pins are solid and there is continuity.
Are these cheap readers useless?
