o2 micro memory card reader sdhci problem

Built-in device is an O2 OZH24 SD/MMC host controller chip for which the Dell web site provides
a native Windows driver.

The sdhci module is loaded but doesn't recognise the hardware as no access is possible. Any thoughts?

Care to test with the latest Karmic 9.10 Alpha release. It contains a much newer 2.6.31 based kernel.

http://cdimage.ubuntu.com/releases/karmic/

If the issue remains, while still running Karmic, please run the following command which will automatically gather and attach kernel debug info to this report:

apport-collect -p linux 427890

[monochromec (monochromec)]

Hi Leann,

Thanks for the hint - unfortunately, neither kernel (32 or 64) will
boot off the CD with the image I downloaded.

As I managed to *build* a 2.6.31 kernel on my 9.04 (running 2.6.28), maybe it's worth giving this
a try without tampering with an alpha distro version. Trouble is, however, I'm still stuggling
with the finer stages of the initrdfs process when trying to install the kernel (the modules are
already in place). Newer kernels (2.6.30 and later) seem to deploy a mechanism called update-initramfs
in order to build the RAM disk for the second stage of the booting process. Unfortunately, I haven't been
able to find any valid documentation for this process on a somewhat generic Ubuntu 9.04 release - any hints or
pointers would be greatly appreciated. Once I'll have this new kernel built up & running, I can check out
the sdhci issue and report back!

[monochromec (monochromec)]

Ok, tried the Karmic alpha-release (6). The 64 bit version doesn't boot at all, the 32 bit version boots but doesn't detect the memory card.

I finally got the 2.6.31 kernel with sdhci to boot but unfortunately, any card inserted in the reader is not detected by the module.

Any thoughts?

[monochromec (monochromec)]

Hi there,

Finally managed to try it with the official Karmic release but still no
luck. It would surprise me if I'm the only one having difficulty with this
driver - any hints for a possible resolution so far?

[monochromec (monochromec)]

BTW: Why is this bug report still marked as "incomplete"? What's missing??

[macaronii (tamrac)]

So it's been a few months since the last post. Any solutions?
Currently i'm hesitating complete ( cold turkey ;) ) switch just because of this thing. The rest of my hardware is very well supported, but this makes the card reader i use very often completely useless.

I believe many Acer and other laptops use this kind of card readers (O2 Micro).

[monochromec (monochromec)]

Nope - I didn't even get an answer regarding the "incomplete" status. Bit disappointing for a community-supported thing I think... :-(((

[macaronii (tamrac)]

Those two seem to be similar issues:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/323159
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/518465
(if so the bug affected user count might be even bigger)

Still, im not knowledgable enough to tell if it is the same thing or something else. I might post lspci output from LiveCD later, if i find the time.
Does SDHCI refers to USB? I think my reader is built in PCI.

The only distant solution i've stumbled upon seems to be some kind of kernel module ( tifm_7xx1) for texas instruments card readers:
http://news.softpedia.com/news/Texas-Instruments-5-in-1-Card-Reader-under-Ubuntu-Edgy-43688.shtml
But it might be completely different device and uncompatible with o2 reader.

[macaronii (tamrac)]

There is something for 4-in-1 reader (i have 5-in-1):

P.S. Is there a way to edit your post instead of creating a new one?
So i can update the previous one with various little bits of information that does not make much of a difference without spamming new comments.

[macaronii (tamrac)]

Now this is funny... since i have several times noticed with different kind of issues that users often are able to do something with live cd but not on installed linux i gave it a try. On karmic koala 9.10 i386 (LiveCD) i pop in my SD and voila! It's on my desktop with all the files on it.

So the promised lspci -v output (only the o2 items):

Lets see what do i get on complete install...

[macaronii (tamrac)]

A fresh install of 9.10 + Latest automatic update it offered and everything works perfectly. Still there was some sort of MMC warning during boot time, but it was too fast to read.

[monochromec (monochromec)]

No such luck here. I tried with the latest kernel (31-20 generic). The kernel module detects the device OK (according to lspci), but the driver fails to notice when a new card is inserted in the reader. Thus no directory is mounted, etc. Please let me know if more information is needed to fix this bug.

Still not working for me with lucid.

[monochromec (monochromec)]

Same here. Kernel 2.6.32-22 and friend (ie. sdhci-pci) doesn't make a difference.

Working on the same issue here:

[monochromec (monochromec)]

Just noticed the following interesting fact: only happens with xd-type cards, SDs are detected and accessed OK.
