Ah!  This shows that your /etc/wpa_supplicant/wpa_supplicant.conf has 
something wrong with it and it can't be parsed.  Please check the file's 
access rights and its contents.  This is what it looks like here:

$ ls -la /etc/wpa_supplicant/wpa_supplicant.conf
-rw-r--r-- 1 root root 33388 Jun 14 15:02 
/etc/wpa_supplicant/wpa_supplicant.conf

Your device has not been initiated, therefore it would not be able to scan 
until then.

Just in case, can you please check that rfkill lists both soft and hard locks 
are *not* on? 

Also, what is your wireless NIC?  It may be worth checking that you are still 
using the correct driver for your wireless chipset?

and that you are using the latest firmware?
