USB Ports not working

[Weaponsmith]

Hi guys,

I am currently using an ASUS G750jh laptop.

So earlier today I plugged in my IPhone to sync it with Itunes but a few seconds after plugging in my mouse (which was connected by USB) stopped responding. The Iphone also did not sync in the end.
Afterwards I did some checking and found that all my USB ports were not working. My mouse lights up when plugged in but it does not respond. My printer that is also connected to another USB port could not be read as well.
I tried plugging in my iphone and now it does not even charge on the laptop. I looked at device manager, and under Unknown Devices - I found that all 3 were located at the USB Ports, and they have a yellow exclamation sign next to them. I tried uninstalling them and restarting my laptop to no effect.

Could they USB controller be fried? Or is it likely that it is a software issue.

Just an update, I realise I have the same problems as these guys:

Which was caused by a Windows Update. This was back in 2014, and perhaps a new update has caused the problem. I am now going through them an uninstalling them.

If you guys are aware of any recent Windows Update that leads to USB problems, please do upate me!

OK I uninstalled a bunch of Updates that came in during the last 24 hours - and my USB port is finally working!!
