You didn't tell us which kernel you're running.  Could you try the 3.14.1 kernel update in updates-testing and see if the rtsx_pci driver loads for this device?

Comment 2 fcbug 2014-04-27 16:21:19 UTC
I was using kernel 3.13.10.

With kernel 3.14.1 rtsx_pci is loaded with rtsx_pci_mms and rtsx_pci_sdmmc.
The SD card is auto mounted and working.

Thank You very much.
