Hi
I had two of my USB ports stop working just a week ago.
I did as suggested and went to Device Manager, and saw that they were shown as not working.
Then right click on the device, select "uninstall" and next at the top or the column, right click on my account name.
Select "Scan for hardware changes" and the ports started working again.
I don't remember where I found this fix but it worked for me.
Hi
