I am following the example tutorial in "Writing an I/O Kit Device
Driver".  I create a matching dictionary via IOServiceMatching
(myDriver).  When I verify the contents of the dictionary the (only)
key-value pair is "IOProviderClass:<myDriver>".

Shouldn't the key part of this be "IOClass" rather
than "IOProviderClass" ?  By using IOServiceMatching() it seems I am
locking myself in to using the "IOProviderClass" key.

If instead I use the call IOServiceMatching("AppleUSBComposite") to
find an Apple driver then IOServiceGetMatchingServices() still doesn't
find anything.  However I know there are instances of AppleUSBComposite
which I can verify via IORegistryExplorer.
