Dell Latitude E6410: Ricoh e822 (rev 03) SD Card Reader Not Working

I've had my laptop for a while but I haven't even attempted to use the SD card reader until today. When I put my SD card in, nothing happened at all. I started searching Google, and it seems that this particular card reader has issues with even the latest kernels, and there doesn't seem to be a fix anywhere. There are some patches mentioned in Red Hat bug databases for Fedora, but I've seen nothing for Arch, and not only that I don't know how to insert kernel packages anyway. I've tried AUR, but it doesn't appear that anything is there.

I'm hoping that maybe someone else has this card reader and has had success? Please reply if so, I'd like to use this if possible.

Here is the vendor string:

02:00.1 SD Host controller: Ricoh Co Ltd Device e822 (rev 03)

Anyone know a work around?

You might have tried this already, but does the output of dmesg show anything when you insert or remove the sd card?

You could try:

watch -n 2 "dmesg | tail"

And see what happens when you insert a card.

My one is Texas Instruments, and works ok for SD cards.

It doesn't seem to change before or after inserting a card.

Looks like there is a patch for Ricoh readers here:
https://bugzilla.redhat.com/show_bug.cgi?id=596475

But I think this may be already in the latest kernel.

Some more discussion here:
https://bugs.launchpad.net/ubuntu/+sour … bug/603445

I don't really know how to get it working, but maybe these guys could help you more:

Thanks, but I'm not sure how to put the patch in Arch. If I knew how I would make an AUR package for everyone to enjoy. I am hoping that there is some sort of easy tweak, or maybe 2.6.36 will have it?
