I am tring to get my cardreader to work with and eye-fi SD card.

My System is as follow:

#uname -a
Linux computer 3.2.0-0.bpo.2-amd64 #1 SMP Thu Mar 15 20:46:44 UTC 2012 x86_64 GNU/Linux

Using the card reader for "normal" SD and SDHC cards seems to work fine. They get registered as devices in /dev/ and can be mounted.

Sadly this is not true for the Eye-Fi Cards (I have tried 2 different models) with the inbuilt card reader. Using the provided USB SD Card Reader and inserting them works and they are mountable etc.

I have tried different methods to get them to run.


Creating a file /etc/modprobe.d/sd.conf
options sdhci debug_quirks=0x40


Creating a file /etc/modprobe.d/sd.conf
options sdhci debug_quirks=1

3) Removing a firewire driver

modprobe -r firewire_ohci

So to sum it up. Normal cards work in the reader but the eye-fi cards don't :(

Does anyone have another idea I could checkout?

  • I have a laptop (Dell XPS 15) with the same card reader, and need to type sudo sh -c "echo 1 > /sys/bus/pci/rescan" after I insert a card for the first time, then it works until I reboot. What happens if you do that?

  • Can you check your dmesg | tail when you're connecting the card?

The Eye-Fi cards seem to require more accurate voltage to power up properly (my own experience with them), I couldn't make it work with my Eye-Fi card reader and it seemed to work with my normal one.

I do have some USB voltage issues on my computer...

I know that practically every camera is able to act as a reader, have you tried to use a camera as a reader?
