Fully patched 16.04 (as of Dec 3rd) still has this problem. None of the above mentioned fixes (lsusb or echo on to /sys/bus/usb/devices/*/power/control) fixes the problem.
I'm on a fairly new Xeon E3 Gigabyte motherboard with an E3-1230. My new Pixel XL is a USB 3 device and when plugged into a USB-3 port I get the: [1596150.752478] usb 2-2: new SuperSpeed USB device number 61 using xhci_hcd [1596150.773530] usb 2-2: New USB device found, idVendor=18d1, idProduct=4ee2 [1596150.773538] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [1596150.773542] usb 2-2: Product: Pixel XL [1596150.773546] usb 2-2: Manufacturer: Google [1596150.773549] usb 2-2: SerialNumber: HT6B70200925 [1596150.775654] usb 2-2: Enable of device-initiated U1 failed. [1596150.775897] usb 2-2: Enable of device-initiated U2 failed. If I plug it into a USB2 port it works. I also had the indentical problem with an Intel NUC, problem is that it has no USB-2 ports. -- 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).
