How do I change COM settings on ASCOM when switching camera to a new port?

[Quetzalcoatl72]

I've been using a 2.0 for my ASI533, the camera also being connected to the ASI120 guider for PHD2 via the USB port on the 533. I realized I should be using the 3.0 port but ASCOM isn't picking up the 533, but the 120 is there when I put it to ASI Camera (1) via NINA. I set up ASCOM years ago and have no idea how it works due to my brain sadly not remembering anything on how it was setup. I have ASCOM diagnostic and profile applications but it doesn't look like I can change anything in there. I hope there is a simple fix for anyone who uses this, thanks.
