Using this "legacy" package.json:

{ "name": "busboy",
  "version": "0.2.14",
  "author": "Brian White <mscdex@mscdex.net>",
  "description": "A streaming parser for HTML form data for node.js",
  "main": "./lib/main",
  "dependencies": {
    "dicer": "0.2.5",
    "readable-stream": "1.1.x"
  },
  "scripts": {
    "test": "node test/test.js"
  },
  "engines": { "node": ">=0.8.0" },
  "keywords": [ "uploads", "forms", "multipart", "form-data" ],
  "licenses": [ { "type": "MIT", "url": "http://github.com/mscdex/busboy/raw/master/LICENSE" } ],
  "repository" : { "type": "git", "url": "http://github.com/mscdex/busboy.git" }
}

... scancode returns

          "license_expression": "unknown",
          "declared_license": "MIT\nhttp://github.com/mscdex/busboy/raw/master/LICENSE",

This is fixed in #1552 following #1403 implementation
