OK; I'm going to hope that Tim Roberts or someone equally knowledgeable can
kick in here as devices really isn't my area. However this looks like it *might*
be doing what you want:

<code>
import wmi

for nic in c.Win32_NetworkAdapter (MACAddress=i.MACAddress):
   for pnp in c.Win32_PNPEntity (DeviceID=nic.PNPDeviceID):
     print pnp.Caption, "=>", pnp.ClassGuid

</code>
