I was searching Google on how to get my SD Card reader to work (It works now, Had to install a dell driver from their website). I stumbled upon a video that had me go into a device manager and update all my "Universal Serial Bus Controllers", by updating them manually. Doing this made my two USB 3.0 ports not get detected at all, I know the ports aren't damage because when i put my external HDD it will still light up but wont get detected. I really need help I don't know what to do.

Heres the video I saw: https://www.youtube.com/watch?v=rvd_q-FJgtw&t=2s

Also my laptop has 4 usb ports (Two USB 3.0 and Two USB 2.0 and the 2.0 Ports works fine)
My PC is a Dell Inspiron 15 2521.
