Public bug reported: A Hitachi 2.5" disk in USB 3 disk enclosure with JMicron chip fails to be connected on Ubuntu Trusty.
The same system was booted with Utopic Unicorn Beta 2 to verify whether newer kernel resolves the problem. Unfortunatelly it does not. The disk was properly recognised only the first time it was attached.
