You could try reverting to previouse driver.
Go to Device Manager and right click the USB controller and click revert to previous driver.
I have a Hp pavilion dv7-1267cl. I was trying to fix my wireless internet capability since the touch button stopped responding. Then all of a sudden all of my USB ports stopped working. I plugged in a flash drive that worked literally a few minutes ago but now nothing happens when i plug it in. I checked in Device Manager and it has the yellow triangle with the exclamation mark next to everything in the "Universal Serial Bus controllers" section. I have already tried to uninstall all of them with the yellow triangle and reboot for the drivers to be reinstalled but it just Fails every single time. I have tried 2 times now. I have even tried pressing F8 during start up and restoring to a previous configuration and the same thing still happens. I would factory restore my computer but i want to save everything on my terabyte first but i cant with no working USB ports!!!
someone please help!
