I have a problem with my laptop. Since I've installed Ubuntu 14.04 LTS in dual boot, my two USB 3.0 don't work anymore.
Maybe you need to know:
My Laptop has 2*USB 2.0 and 2*USB 3.0. One of the USB 2.0 is defect, I don't know why, it doesn't work under Windows either. The two 3.0 Ports work under Windows (they charge my Phone and I can connect my mouse & USB stick to them). The 2.0 port works fine, too. In Ubuntu, the 2.0 port works excellent, too. But the 3.0 Ports don't. Whenever I plug in my Phone, it says that it's charging, but it doesn't detect that it's connect to a Laptop/PC (No USB Debugging icon and no option to enable mass storage). When i plug my mouse in one of the 3.0 ports, the laser (or whatever it is) on the bottom of the mouse flickers, but it doesn't work. When i plug in an USB, it doesn't connect. Before Ubuntu 14.04 i had 13.04 and everything worked as it should (except the USB 2.0 port, of course).
This is the output of lsusb
with plugged in my mouse and my phone to my 3.0 ports:

This is 'lsusb' with nothing plugged in:
