USB Port Issue - Power Surge on Hub Port
I have a dell xps 15 9550. I plug a 4 port usb hub into the usb port as i use wireless mouse, and use keyboard and thus need a lot of usb hubs. I never had an issue at all. Just recently i had to charge a poweradd... this is a piece that charges your iphone. Thus in order to charge the poweradd, you need to connect it to an outlet. I had thought you could charge it to a usb port on your laptop.. .first off can you do this or not? Well the thing was i wasn't even sure which cable to plug into it as when i used a cable to plug into it and then tried to plug into outlet, it didn't work. It felt like that was not the cable to connect to the poweradd as it didn't fit. But i tried anyway. I then decided to plug it into one of those port hubs , i only had one available. Well not only did it not work, i got a message power surge on hub port message and my 4 port hub immediately stopped working.
I unplugged the 4 port hub and then plugged it back in and it didn't work. After a while, i got message that the usb port didn't work and to click okay. Says device is not working properly. But after a while it does work. My issue now is everytime i turn on my laptop, i cannot use my wireless mouse or anything else connected to the 4 port hub because it doesn't work at first. However after you wait for a few minutes, it would have that same message of the device is not working properly. You wait a bit, then it doesn't work. Then finally it shows the same or similar message and now it works.
The thing is did i damage my usb port on my dell xps 15 9550 laptop? Or did i only damage the 4 port hub? Because if its the 4 port hub, i would just buy a new one. However, i think its the actual port? Does anyone know how to fix this issue? Did i damage my computer? How do i fix this issue?
Also there are 2 usb ports on the laptop. I never used the one on the left side of it though. So if the right one got damaged, does that mean i could only use the one on the left? The left one is not convenient since its right next to the charger plug in. Also if my 4 port hub is damaged etc, do i risk damaging the other port on the left?
Also what happens if both usb ports no longer work on the laptop? Then how would you be able to use a laptop? Could a repair shop fix a usb port?
