I use D-Link DWA-110 WiFi usb dongle. It used to be working well, but after some config changes I broke something and now when I plug the dongle in I see it in lsusb output, but wlan0 isn't created and the led on the dongle doesn't light.

What to check out?

~ > uname -a
Linux Distress 3.2.0-56-generic #86-Ubuntu SMP Wed Oct 23 17:31:43 UTC 2013 i686 i686 i386 GNU/Linux

dmesg shows
