Lock the screen on OS X when some USB device is removed.
This tool relies on the usage of the default ctrl+cmd+q shortcut to lock the screen.
Run system_profiler SPUSBDataType in your terminal and look for your USB device.
Copy the Vendor ID and the Product ID after the 0x part and paste them in the installation command.
./install.sh <vendor-id> <product-id>
After the install detach your usb device to trigger the script. This will ask for "bash" to have access to "Accessibility", do so to fully enable the script.
./uninstall.sh <vendor-id> <product-id>
