This is not a very good idea.. ctrl_interface is supposed to be a path
for a directory whereas this looks more like the path to the binary..
Normally, this should be /var/run/wpa_supplicant.

This is caused by the invalid ctrl_interface configuration.

Hmm.. Are you sure this is using Host AP driver? This "IEEE 802.11-DS"
string would normally be "IEEE 802.11b" with Host AP driver.. Which
wireless LAN card are using? What does 'dmesg' show after the card has
been initialized?
