This is a lightweight macOS implementation of the lsusb command, similar to the Linux usbutils package.
It uses Apple's IOKit framework to list connected USB devices.

• Lists USB devices with Vendor ID, Product ID, and Product Name.
• Installs as lsusb in /usr/local/bin so it behaves like Linux.
• Includes a manual page (man lsusb).
• Simple Makefile for build, install, uninstall.

Clone and build:

make build
sudo make install
