Ubuntu 14.04 doesn't recognize any of my Android devices anymore. (Tried with the Nexus 7 and Galaxy Nexus)
I thought this was an MTP or ADB-problem, but connecting / disconnecting the devices doesn't even change the output of lsusb
or dmesg
at all.
It's like the devices aren't even plugged-in. However they both charge normally, when I plug them in, so I can't imagine having a cable-problem or a problem with the android devices themselves.
(I've tried it with usb-debugging on and off on both devices – no difference)

I have problems with my Ubuntu GNOME 14.04 installation recognizing my Nexus 7 at times, too. This is what works for me:
adb devices
(you might need to be root).
