Debug releases of the IOUSBFamily kernel extension are used to provide information about USB device and interface detection, driver and interface matching, driver loading and information generated as a result of normal and abnormal conditions.
Unique debugging versions of the IOUSBFamily kernel extension are available for the different Mac OS X releases. It is important that you install the correct version of the IOUSBFamily kernel extension or you might find that the system will panic during startup or that your USB keyboard or mouse may not function properly.
In the table below, match the IOUSBFamily kernel extension version with the appropriate debug version of the IOUSBFamily and download the corresponding disk image.
You will download a disk image which contains a PackageMaker file and a ReadMe. Follow the instructions in the ReadMe file explicitly.
The ReadMe file may not indicate that your version of Mac OS X is supported. This occurs when there are no changes to the IOUSBFamily in System Updates. Check that you are using the IOUSBFamily log version matched to your Mac OS X release, listed below.
In all of these releases, the corresponding version of USB Prober is installed in the /Developer/Applications/ folder.
IMPORTANT: If the incorrect version of the IOUSBFamily kernel extension is installed, the system may panic on startup. Make sure that you have a way to correct the problem, before beginning the installation. You might use a bootable FireWire storage device, or a different bootable partition. When booted, you can use Terminal to restore the original IOUSBFamily kernel extension back into the /System/Library/Extensions/ folder of the broken partition.
