Why does Ubuntu not detect my SD card?
Run these commands from a command prompt:
sudo modprobe -r r852
sudo modprobe -r sdhci_pci
sudo modprobe r852
sudo modprobe sdhci_pci
This uses modprobe to unload and reload the device drivers (in this case kernel modules) to automatically detect the SD card into the kernel.
