Again, this is NOT a LINUX problem. This is a manufacturer of your USB 3.0 device problem. They (the manufacturer) is NOT following the xHCI USB 3.0 specs and therefore the device does not work properly. In other words, it's likely the external HDD, not the machine, nor the O/S (Ubuntu).
The reason your USB 3.0 device works in Windows, is that (a) either Microsoft wrote some hacky drivers for the bad device, or (b) the manufacturer of the device submitted a "driver" to Microsoft so that it's sub-standard firmware/hardware would work on Windows. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1242321 Title: USB 3.0 Harddrive not recognised Status in linux package in Ubuntu: Confirmed Bug description: Ubuntu is not recognising any device plugged into any USB 3.0 ports. Sometimes Ubuntu will freeze for a few seconds when you plug something into a USB 3.0 port; when Ubuntu comes out of the freeze, the device is still NOT recognised. No problems with USB 2.0 ports and devices. The USB 3.0 on this computer only works in Windows 7 (I'm dual booting Ubuntu 13.10 and Windows 7, both are 64-bit).
