Hi,

I've recently bought an Asus N550jv laptop but I cannot get the SD card reader to detect any cards in Ubuntu 12.04. I know it uses the RTS5139 module but even with this loaded (and it is loaded by default), no cards are detected. Listing the devices, an try appears (/dev/sdb) when the module is loaded and disappears when the module is removed, so the module appears to work, at least partially. Is there anything else I need to configure to get the system to recognise that a card is inserted?

Thanks,
John.
