This is about connman's driver: plugins/wifi.c along with gsupplicant
And that can happen if wpa_supplicant dbus service is not found.

Try:
stop wpa_supplicant, and connman.

in a terminal start wpa_supplicant un foreground with -u -ddd

in another terminal start connman in foreground as you did.

See if wpa_supplicant gets contacted. Something tells me it is not.

If that's the case: then it's most likely a dbus config issue for 
wpa_supplicant.
Check /etc/dbus-1/system.d/wpa_supplicant.conf

Tomasz

Tomasz,

you are right. I launched wpa_supplicant and then connmand. Nothing has 
appeared on wpa_supplicant stdout.

This is my wpa_supplicant dbus configuration file:

Do you think there is something wrong?
