To determine the latest version, compare the overall build number (in parenthesis after the model name)
and the GPD number (in the Driver Files: field). If the overall build number has increased, this is the
latest version of the driver.
If the overall build number is the same, check the version number of the GPD file. The driver that has
the highest GPD version number is the latest driver.
