I have a Dell N5110 laptop with Ubuntu 14.04 LTS on it. My internal card reader is a Realtek RTS5138 is not working (when I plug-in an SD card nothing happens).
I tried this solution (although it is for Realtek rts5139 and I found an rts5139 module on my system) but it didn't work.
When I plug in and SD card in the internal card reader it appears in the lsusb
output:

. If it's USB, is it plugged in and enabled? Otherwise it might be connected directly to PCI. Try finding it witlspci
.sudo dmesg
andlsblk
just after you put a memory card in the reader?
