USB Ports do not work

[LukeVail]

What I’ve tried: All my drivers are up to date, HP diagnostics can’t find anything wrong, my devices work properly plugged into any other computer.

What I think it is: I think all of my USBs got shorted but I have no idea how to confirm this theory. I have plugged in one 5V/60Amp mouse that hardly works but will occasionally freaks out and begins moving on its own(doesn’t do it on other devices), one 5v/100Amp mouse which will cause the computer to continuously connect then disconnect from the mouse but will not actually connect, a 5v/75amp power cord used to control an arduino

What I need: I have recently applied to work at a computer repair shop so I’ll have the opportunity to replace parts but I would like to confirm my theory or hear from others. Is there anyway to test the output of my USB drive or find the cause of the broken USBs

TLDR: USB drives no work, plox help

Edit: I just used a stripped wire and my multimeter and it was only reading out 4.53 volts, any suggestions on how to fix??

It has been decades since fuses were used to protect USB ports.   Chips now-a-days have built in protection but nothing is  perfect.

Unplug system from wall and remove battery if laptop.  Remove all USB devices except keyboard.  Press power on to discharge anything left in power supply. After 10 or so seconds connect power and turn on.  This should reset the the built in protection. 

The following article is good

the two test items at the bottom are good.

I have a "USB tester" that can show if the USB-C charging device is working or not.  That is not the same as a tester if the USB port is working.  When the author writes not to use an input device for output that is what he is referring to.

Apple and Garmin among other manufacturer check to see if you are using their "blessed" cable or charger and slow down or prevent charging and I got a tester for that purpose.   Garmin is especially bad.

Just because the voltage is present does not mean the port is working. It is possible but unlikely that the data + and - contacts are bad.  I could see one port being corroded but not all.
