10   Iterates through the list of known onboard devices. If a device is
11   found with a matching <em class="parameter"><code>vendor</code></em> and <em class="parameter"><code>device</code></em>, a pointer to its device
12   structure is returned.  Otherwise, <code class="constant">NULL</code> is returned.
13   A new search is initiated by passing <code class="constant">NULL</code> as the <em class="parameter"><code>from</code></em> argument.
14   If <em class="parameter"><code>from</code></em> is not <code class="constant">NULL</code>, searches continue from next device.
