No cardreader support for O2 Micro, Inc. Device [1217:8520]

Set to incomplete, waiting the driver shows up in mainline.

Had a "How to submit patches" tech talk with O2Micro engineers, they submitted their first version but rejected, maintainer suggest they wrote a new module instead of adding ~200 lines into general module.

By now, their patch v2 is waiting for review.

Affecting 201307-14017 Dell Latitude E5440

I can confirm this bug on my Dell Latitude E6540 using kubuntu 13.10.

Affecting 201307-13941 Dell Latitude E5440

With O2Micro's permission, I did some modification and resubmitted the patch to mmc-next.

Also affects Dell Latitude e7440 with Ubuntu 12.04.03 ... 3.8.0-34-generic #49~precise1-Ubuntu SMP Wed Nov 13 18:05:00 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Thank you.

And a list of other notebooks which are likely to also be affected:

http://www.ubuntu.com/certification/catalog/component/pci/1217:8520/

Begs the question ... how can these systems be listed as certified by Ubuntu if part of the hardware obviously doesn't work?

Hi, @bengtan

1, we deliver drivers in OEM projects, out of kernel.
2, this bug can be fixed by BIOS too.

in mmc-next now, waiting next week's merge window.

remove raring branch since it's almost eol, no enough time.

I agree that 13.04 is reaching EOL.

However, the EOL for the Raring HWE Stack is April 2017 because it's in 12.04.3, yes?

See https://wiki.ubuntu.com/Kernel/LTSEnablementStack

"The natural support duration for the 13.04 Raring Ringtail release is now 9 months. We will however commit to supporting the Raring HWE stack in 12.04 from the time of the 12.04.3 point release until the 14.04.1 time frame. "

Quoted from https://wiki.ubuntu.com/Kernel/LTSEnablementStack

Thanks for reminding, @bengtan

Patches were pushed to mmc-next for 3.14.

patchset for trusty, saucy and lts-raring are submitted to kernel-team maillist.

Hi,

I recently installed a linux kernel update, but it doesn't look like it's fixed this issue. I'm on 12.04.3 LTS with Raring LTS (I think):

Linux MXC-062 3.8.0-35-generic #52~precise1-Ubuntu SMP Thu Jan 30 17:24:40 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Has it been released for this "stream" of the kernel yet? I don't quite understand the subtleties of the different kernel projects on launchpad.

Thanks.

@bengtan

check linux-lts-raring's precise stream, not released yet by now.

@Adam Lee: Understood. Thanks.

I installed the 3.13.0-6.23 (https://launchpad.net/ubuntu/+source/linux/3.13.0-6.23) kernel which supposedly contains the fix and confirmed that the affected card reader (O2 Micro) indeed works properly afterwards.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-saucy' to 'verification-done-saucy'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

verified with saucy 3.11.0-18, positive

verified with lts-raring 3.8.0-37, positive too

#25 and #26 are tested on ThinkPad W540

Hi,

I've just updated the kernel. Works now, and issue resolved for me.

Platform:
Dell e7440
Linux MXC-062 3.8.0-37-generic #53~precise1-Ubuntu SMP Wed Feb 19 21:37:54 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Thank you.

Dell Latitude E6540(CID 201306-13679) tested on linux-lts-saucy (3.11.0-18.32~precise1)

the cardreader works now.

But for some of mmc cards it could not work normally, this issue was filed as the bug report LP: #1296598

On a Latitude E6440 I get:

[ 1.149244] mmc0: Unknown controller version (3). You may experience problems.

06:00.0 SD Host controller: O2 Micro, Inc. SD/MMC Card Reader Controller (rev 01)

Is that normal?

@Rob, may you please paste your "lspci -nn" output here?

@Rob, that output is OK. Please report bug if you find the "experience problems", thanks.
