QGroundControl v3.4.4 onnect to comm ports on my PC

I am trying to connect a Pixhawk4 version 2.4.8 to QGroundcontrol on two different computers and and it can’t see my comm ports. I go into device manager and it shows comms 3,4,5 but in the software it says “no serial ports available”. Can anyone tell me what I need to do to get the software to see the ports?

I figured it out. I had to change USB cables for the software to work.
