Documentation

parseDb :: String -> Maybe IDDB

Source

Construct a database from a string in the format used by usb.org.

staticDb :: IO IDDB

Source

Load a database from a snapshot of the usb.org database which is supplied with the package.

fromFile :: FilePath -> IO (Maybe IDDB)

Source

Load a vendor database from file. If the file can not be read for some reason an error will be thrown.

fromWeb :: IO (Maybe IDDB)

Source

Construct a database from the list of companies available at http://www.usb.org/developers/tools/comp_dump. The website informs us that: "Remember this list changes almost daily, be sure to get a fresh copy when you use the tools". However, the list seems to be quite stable. Using this function more than once a day is probably overkill.
