As always a kernel log could help or output from dmesg command. Also can
you run following commands:

$ ls /sys/bus/sdio/devices
$ cat /sys/bus/sdio/devices/*/modalias

Hi Paolo,

Interesting. Now if Google search is correct the vendor id for this
device indicates this is a Realtek (v024C) WLAN (c07) device. So what
makes you say its linux id is 02d0:a9a6?

In upstream linux I do not see any SDIO device drivers in realtek
folder. Maybe Larry can provide clue/hint if a driver for this device is
publicly available somewhere.

Arend

You are not boring anyone, but you really should ask the manufacturer.
All I can say is your sysfs shows there is only one SDIO device with
vendor id 0x024c (Realtek) and class 0x07 (WLAN) so brcmfmac will not be
probed for that as all aliases below for brcmfmac are listing vendor id
0x02d0 (Broadcom). That is all the command below indicates.

Paolo,

The only Realtek SDIO device in common distribution is the RTL8723BS, which has 
been packaged with some Intel processors, and may now be part of other SBC's. 
This driver has been in staging since V4.12. It handles SDIO Vendor code 0x024c 
with device codes 0x0523, 0x0623, 0x0626, and 0xb723. If your device is one of 
these, then you only need to build a kernel with this driver enabled.

I have had very little to do with this driver, other than posting the original 
version on GitHub. From there, many users have modified it until it was 
submitted to staging by Hans de Goede of RedHat.

He has device id 0xb723:

paolo@paolo:~$ cat /sys/bus/sdio/devices/*/modalias sdio:c07v024CdB723

So that driver should at least try to probe his device.

Hi Arend on debian is avaible only an experimental trunk of mainline 
4.12 and the RTL8723BS module is not activated i suppose , i tried this 
guide 
https://github.com/hadess/rtl8723bs/wiki/RTL8723BS-module-building-instruction-for-Debian-GNU-Linux 
but doens't NOTHING the make command ( obviously i installed all the 
necessary ) in the zip there are the firmware  *.bin maybe i must wait 
the 4,12 backports ....i could compile my own kernel but in this moment 
ain't much time.....

I built my own kernel in the debian way , very simple and amusing ,  i 
removed some modules not interesting ,  i set to M rtl8723bs and all ok 
!!! only a bit long the building with my dual core ,The bluetooth needs 
rtk_hciattach of Larry Finger , however strange the new debian kernels 
above all 4.13rc have not set rtl8723bs module.
Best regards

rtk_hciattach
