I am using Windows 8.1 on an ASUS X550C. All my USB ports (2 USB2.0 and 1 3.0) have suddenly stopped working. External drives when connected show a light but are not recognised. Graphics tablet and printers also do not work, though they do when attached to another printer. I have not recently done anything by way of software installations. I have done a clean boot, but no difference.

I have ensured the latest Windows Updates are installed. In Other Devices, the USB Root HUB (xHCl) has a yellow exclamation mark next to it. Searching for an updated driver produces no result. Everything else on the machine seems to be working ok. Advice please.
