Hi Sean,

This is new with 10.1. This means that you've not declared your dependency on the module containing the superclass in the OSBundleLibraries property in your driver's plist.

An updated release note on kernel extensions was recently posted at <http://developer.apple.com/techpubs/macosx/ReleaseNotes/KernelExtensions.
html>. This should give you what you need although the IOAudioFamily is not explicitly mentioned.

Good luck,

When attempting to create a symbol file to debug my driver, as described
in "Debugging a Device Driver With GDB", I get the error message below.
The driver is dependent on IOUSBFamily and IOAudioFamily, both of which
appear to be loaded. And the driver loads fine using kextload. Any
ideas?


kmodload: Can't find superclass for _19AppleUSBAudioDevice :
