SD Card reader is not accessible

Ask Fedora

Hello everyone,

Sorry in advance if it’s the wrong forum to ask, but since I only use Fedora, I’m starting from here.

My SD Card reader is not working on my laptop, although it seems it’s already supported by the kernel.

The SD card reader version from lspci is:

0000:2c:00.0 Unassigned class [ff00]: Genesys Logic, Inc GL9755 SD Host Controller (rev 01)

I have checked on linux hardware and in the Linux Kernel repo, and it says that it should be supported since Linux 5.4.

I have also checked dmesg when I insert my SD Card in the reader,
but there is absolutely no logs coming out.

The only log I have is from the Logs Gnome app, which says:

sdhci-pci 0000:2c:00.0: Unable to change power state from D3cold to D0, device inaccessible

I have this error since I started to use Fedora on this laptop with the kernel 6.10. The new 6.11 version didn’t change anything.

Thank you for your time !

Have a nice day,
boeing60.

Hello again,

I have the same laptop and the same problem. The only difference for me is that dmesg gives me

sdhci-pci 0000:2c:00.0: Unable to change power state from D3cold to D0, device inaccessible

I am on Fedora 41 and kernel 6.11.7. BTW @boeing60 did you manage to setup face identification or the DialPad?

Hello again!

I think that in my case, gnome log results are coming from dmesg.
Because if I check dmesg entire log output, I also find the same message as you.
When I say that dmesg give me nothing, I mean when I insert my SD card in the laptop reader, there is no new log. But since the device seems to be inaccessible, I guess this is expected.

But thank you a lot for confirming it! At least now we know that this is not a simple defect on my unit, but a real problem with the Linux driver (or maybe the Asus BIOS who know…).
I will try to run Ubuntu 24.10 on live ISO to see if the problem is still there.

Unfortunately IIRC, GNOME (I don’t know about KDE) doesn’t support Facial identification, only fingerprint unlocking. If you really want face recognition to unlock your laptop, you can try howdy. I used it on my previous laptop and it work pretty well at the time.
But this days, I would rather have a more integrated solution (out of security concern and stability) than a third party software. So, I guess we can wait a while :sweat_smile:.
About the DialPad, sorry but I haven’t really search about it. I don’t use this feature on Windows at all so I don’t miss it that much. And I don’t know if this kind of peculiar Asus feature are usually well supported on Linux, or not.

Have a nice weekend,
Clement.
