Why does Ubuntu not detect my SD card?

Question

I can't mount my SD card. I'm using Ubuntu 12.04 LTS on an Asus K55V (Intel), and I have a sd card slot, but Ubuntu doesn't detect when I put a SD card in the slot. Not Ubuntu nor other program.

Make sure there's a formatted card in the slot and run the following commands: "sudo fdisk -l" and "blkid". Paste the results back into your question so that we can have a look. — fabricator4, Dec 01 '12 at 19:20
Have you checked the filesystem if the card is exfat you have to install exfat fuse for mounting it. — Chinmaya B, Aug 14 '15 at 10:51

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.

Source codes

r852 driver: Ricoh 85xx xD/smartmedia card reader driver
sdhci_pci driver: Secure Digital Host Controller Interface PCI driver

Doesn't do anything for me in Ubuntu 12.04. – Cerin Feb 06 '15 at 19:15
Works on Ubuntu 14.04 64-bit after running the command, then taking out the SD card and putting it back in again. Thanks a ton! – Ads20000 Feb 07 '15 at 17:04

This doesn't do anything on 18.04 and isn't any better than rebooting. – Michael Cole May 01 '18 at 18:15

For Broadcom Corporation BCM57765/57785, in addition to the answer below, I had to add lines to modprobe.d (before commands above)

$ sudo sh -c 'echo options sdhci debug_quirks=0x40 >> /etc/modprobe.d/sdhci-pci.conf'

AND

$ sudo setpci -s 00:1c.2 0x50.B=0x41
