A database of USB identifiers.

Databases with vendor names and identifiers can be loaded from string, file or directly from http://www.usb.org.

Example usage:

module Main where

import System.USB.IDDB
import Data.ByteString.Char8 (pack, unpack)

main :: IO ()
main = do -- Acquire the default database
          db <- vdbDefault
          -- Print the name of vendor 0x1D6B
          putStrLn $ 'maybe "unknown ID!" unpack
                   $ vendorName db 0x1D6B
          -- Print the ID of "The Linux Foundation"
          putStrLn $ maybe "unknown name!" show
                   $ vendorID db (pack "The Linux Foundation")

EBNF grammar of the textual representation of a vendor database:

  vendor database = {row};
  row             = vendor id, "|", vendor name;
  vendor id       = natural number;
  vendor name     = ASCII string;
  natural number  = positive digit, {digit}
  positive digit  = "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9";
  digit           = "0" | positive digit;
