Clicking on "Get camera info" in pmca-gui, I get the following error:

I got it to work by installing libusb

brew install libusb

I got it to work by installing libusb

brew install libusb

This got me going in the right direction, but I also had to do this: (on m2 mac)

ln -s /opt/homebrew/lib ~/lib
