Hi,
all rollback buttons are greyed out.
I have tried update driver-buttons, and 1 port USD 2.0 started working for memory sticks and external hard disk, and charging the phone, but not for the mouse.
My two 3.0 ports are not yet working, when trying to update, the message is: you already have the best driver.
Restarting made no difference...

Roll back any/all new drivers that were installed (to the ones you had before) and retest.
