Some time ago I've been able to connect my "Smart"phone to my Ubuntu 14.04 PC as mass storage device with an micro USB cable hitting the ~"Activate USB storage" (translated) button in the notifiaction pull-down panel which appeared after the cable has been plugged in. Now, establishing an USB connection is tried for > 3 minutes and then times out; the animated waiting icon (spinning circle in which the button to activate the USB storage is transformed to) changes back to the button to activate the storage. Some infos:
- occurs 100 % of the tries
- restart doesn't help
- cable seems fine because charging works
- Android 4.0.4 on SansuiCosmic SP 1001 trying to connect to Ubuntu 14.04 with Linux 3.15.9 without problems with USB experienced so far.
