Camera and flashdrive issues on MacBook running POP os

Hey all! I have installed Pop on my 2015 Macbook pro. I have had it about a year now. Love it! I originally had a problem with the camera for skype. I got help in this forum that got it going by loading the drivers and firmware and such. That fixed it. Then when I upgraded to the newest version of Pop it stopped working again. I am also having problems with the usb ports reading my flashdrives. Any advise would be awesome. I’ve went back and tried doing all the previous commands in the terminal that the original forum gave me twice and still no joy?
