Internal microsd card reader does not work in Ubuntu 17.10

[funicorn]

Ubuntu 17.10 x86_64 of Wayland-Session is running on a HP Envy 13-ad1xx notbook with a internal microsd card reader. The system gives no response when inserting different micro sd cards, which work fine on Windows 10. I report this bug in hope that the upstream may notice and make some change on the suited driver or kernel module. I would provide more information under further direction.

According to `lspci` output, the model name is 'Alcor Micro Device 6625'.

`udevadm monitor --env` gives no related events when inserting or pulling out the microsd card, in which only thermal_zone changes are recorded. No related events are recoded in /var/log/kern.log either.

With sd card being inserted, `sudo fdisk -l` and `sudo blkid` gives no related information. The outputs are all about partitions on the local disk. No sdhc or mmc device is found in /dev/ either.

The only implication now is the system notice the existence of the card reader, in terms of `lspci` outputs, the '01:00.0 Unassigned class [ff00]: Alcor Micro Device 6625', even when a sd card is inserted:

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

[Joseph Salisbury (jsalisbury)]

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

The bug exists in ubuntu 16.04. It still exists in the mainstream kernel v4.14-rc6. I haven't tested in kernel v4.14-rc8.

[funicorn (funicorn)]

OK. I have tested it in the newest mainstream kernel v4.14-rc8. There is nothing changed.

[Kai-Heng Feng (kaihengfeng)]

Unless someone writes driver for the card reader, it's not going to work.

[Bao Pham (baothaipham2017)]

Please someone write the driver for this card reader.

[sfc (sfc-0)]

You could try this driver: https://github.com/josch09/ampe_stor. From the code, it seems supporting AU6601, AU6621, and AU6625, but it's not working on my envy 13 ad110tu (AU6625). It can detect the card, and get the capacity, but then many errors will occur and finally the reader dies. Maybe it will work on your device.

[sfc (sfc-0)]

Also see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1270676/comments/80 to install it with DKMS.

[funicorn (funicorn)]

@sfc Could you explain a little more how exactly to use the dkms.conf file? Should I put the file in the same ampe_stor directory?

[sfc (sfc-0)]

@funicorn Yes. Put that dkms.conf in the same ampe_stor directory and use "dkms add" to add it. Please refer to https://help.ubuntu.com/community/DKMS and https://github.com/dell/dkms for detailed instructions.

[funicorn (funicorn)]

@sfc I installed the driver and had it loaded, however the card reader remains unassigned after reboot. Maybe I should wait for some kernel update fixing this issue. Thanks a lot for help.

[Neculai Dan Ciprian (enkumber)]

Still no way to fix this?

I suppose this is a duplicate of bug #1270676
