i have a problem with one of my android devices which is suddenly not recognized anymore. It worked yesterday, but since of today the device won't be listed anymore in the explorer. The cable is fine since it is working with all other devices that used to work.
Actually i have no idea where to start to get it working again. How could it suddenly stop working? Btw. i haven't done any updates in the meantime neither to the device nor the Ubuntu machine which makes it even weirder...
I am on Ubuntu 14.04, device is a Samsung A3
Thanks for your help.
