Answer 1

The error message is saying that the configure script cannot find the (libusb library). This can happen for a few reasons:

1. The libusb library is not installed.
2. The libusb library is installed in a non-standard location.
3. The configure script is not using the correct flags to find the libusb library.

To fix this, you can try the following:

Make sure that the libusb library is installed. You can do this by running the following command:

brew install libusb

If the libusb library is installed, make sure that the configure script can find it. You can do this by setting the PKG_CONFIG_PATH environment variable to the directory where the libusb library is installed. For example, if the libusb library is installed in /usr/local/lib/pkgconfig, you would set the PKG_CONFIG_PATH environment variable to /usr/local/lib/pkgconfig.

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
