Hi guys,

I have a Dell Latitude E6330 laptop. All the usb ports stopped working suddenly. It doesn't recognize any
device plugged in. I have reinstalled Windows but still not working. But you are able to use the usb ports of
a DOCKING station when you PLACE the laptop on.
Any SOLUTION for me to fix my usb ports not working?

Thanks. Many laptops have a USB daughter board. The fact that it works with docking station which would use the same USB controller MAKES me think you have a damaged daughter board. You would need to open laptop to see if this is the case or with make/model look up to see if a picture of the inside or a parts break down is available to show a daughter board.

 I have had to replace these before on laptops where somehow something was plugged in and the USB port got struck and bent damaging the daughter board inside such as child running through a mouse CORD and pulling whole laptop off of the stool that it was resting on etc. This required a daughter board and a new hard drive to repair.
