What works for me is powering on my laptop (HP Probook 4430s, Core i-5 2410m with 16gb dual-boot win7/ubnt 16.04.1) with the USB 3.0 device already plugged in before boot. Seems to have something to do with the voltages. Try this!

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).
