|Construct a database from a string in the format used by usb.org.
|Load a database from a snapshot of the usb.org database which is
supplied with the package.
|Load a vendor database from file. If the file can not be read for
some reason an error will be thrown.
|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.
