I bought an Asus X550VX laptop a few weeks ago and installed Ubuntu 16.04 alongside Windows 10 on it. For a week or so everything worked fine, until one of the USB 3.0 ports stopped working. Soon after that, the other port stopped working too. The one USB 2 port still works fine. When I connect my phone to a USB 3 port it charges, but Ubuntu doesn't recognize that a device is connected. My wireless mouse doesn't work either on those ports.
I've googled around but nothing seems to help. I've updated my bios and added a "pci=nomsi" line to grub file. Any other suggestions?
