My USB Port isn't working - basic troubleshooting not helpful?
I have a Toshiba Satellite U50D which has 2 x 3.0 Ports and 1 x 2.0 Port. I recently plugged in my iphone 5s into one of the 3.0 Ports and my laptop shut off straight away. I thought maybe it caused a surge of sorts. Since then both my USB 3.0 Ports haven't been working. I've tried the basic troubleshooting of uninstalling the drivers and such but nothing seems to work. Do I need to replace the ports or can they be fixed without cost?
Added (1). The USB 2.0 Port still works just fine but is on the other side of the laptop.
Maybe a fault on the Iphone or the cable could have destroyed the USB controller board.
- Why port forwarding on port 80? I have a foscam home security camera and it needs port forwarding on port 80 if I want to use my iphone to view it from outside. Surely enough, it works as soon as I open that port. But isn't port 80 open by default? Else how could I view http websites in the first place. I don't get it. It's already open so why open it again?
