RealTek RTS5286 PCI Express Card Reader trouble

A card reader on my laptop (Debian testing amd64 4.9.6-r1t) does not work. I remember this card reader worked quite a while ago. There is not much trouble with this module with web search.

lspci says

Code:

03:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5286 PCI Express Card Reader (rev 01)

Its driver is rtsx_pci, which is built in.
lshw reads:

Code:

description: Unassigned class
product: RTS5286 PCI Express Card Reader
vendor: Realtek Semiconductor Co., Ltd.
physical id: 0
bus info: pci@0000:03:00.0
version: 01
width: 32 bits
clock: 33MHz
capabilities: pm msi pciexpress msix vpd bus_master cap_list
configuration: driver=rtsx_pci latency=0
resources: irq:26 memory:f7400000-f740ffff

syslog reads:

Code:

May 29 19:45:44 Pen15guin kernel: [    1.243097] rtsx_pci 0000:03:00.0: rtsx_pci_acquire_irq: pcr->msi_en = 1, pci->irq = 26

But nothing happens when card is inserted. (dmesg stays quiet!!)

Other usb ports work well (mouse, memory stick)

I guess that a correct kernel module recognizes hardware, and has irq assigned.

Why nothing happens? Could this be hardware failure??

I appreciate any suggestion.

Thanks in advance

Supposed to be in these kernels. https://cateee.net/lkddb/web-lkddb/MFD_RTSX_PCI.html
That doesn't mean your kernel has it or is using it correctly. See what modprobe command shows. May have to blacklist or add in.

Just for grin's I'd try a few live media booted distro's to see what they do. We tend to assume the card reader is OK and the sd card is OK but not proven yet.

Thanks for your reply.

With 4.9.6-rt1,
I have tried both kernel-built-in and module. None of them works. modprobe says irq message only (shown in message #1), no error.

I also tried with kernel 4.8.11-rt5 without success.

I will update.

cheers

Apology for delay.

I followed the links. Not much progress.
Using rts_pstor (from github) did not resolve. (compiled well, no error on load. But did not work with the reader.)

I will update

cheers.

Some of the Realtek card readers are in "staging drivers" in the kernel config, and may not be enabled by default.

Thanks for your post.

I checked the one under staging driver (rts5208) without success.

I also checked old kernels, 3.16.7-ckt11 4.8.11-rt5, without success.

I will update,

cheers

Here it's in staging: http://cateee.net/lkddb/web-lkddb/RTS5208.html

Try

Code:

$ grep 5208 /boot/config-kernel_version

and see if it's enabled.

Thanks for your post.

Yes, it was there. When I modprobe'd the module, a message saying that something like "use rtsx_pci" appeared.

AwesomeMachine · 06-19-2017, 03:33 PM

OK, good. We're getting closer.

Anyone found a solution for this problem?

I got the same issue with the same sd card on my Dell latitude 7490 running Debian Buster

Hya,

For some reason, (after several system upgrades), the card reader works, if rtsx_pci is loaded. (need to modprobe rtsx_pci when not loaded)

Even when precompiled image is used, situation is same.

My penguin does not complain as yours, (-110... SD card).

cheers

What distro do you use? I run Debian Buster non-free

kaz2100 · 02-13-2019, 01:39 AM

Debian buster(amd64)

cheers

After a long interval, the card slot is dead again.

Current system, Debian testing, kernel 5.10

Even when rtsx_pci is loaded, nothing happens, (no trace in syslog, messges, kern.log...)
