External DVD drive not working.
I have an LG external DVD drive and a Dell one. Both used to work perfectly fine on both my 2016 15.4" MBP and my 2019 16" MBP. Tried to use them yesterday on both computers and they are not recognized. If I switch to Windows 10 in boot camp, it makes the mounting sound over and over, but does not mount. Both computers are running 10.15.7 and this is a new issue. We are using official Apple dongles. Both disc drives work fine on my Dell laptop. Any suggestions?
