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 Regards, Arend
paolo@paolo:~$ ls /sys/bus/sdio/devices

paolo@paolo:~$ cat /sys/bus/sdio/devices/*/modalias sdio:c07v024CdB723
paolo@paolo:~$ sorry for previous mail ....ls was from another pc....:-[
it seems the system see only the card where the system is installed

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.

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.

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.

Regards,
Arend
