Comment 6 for bug 420834

I'm trying to extract from Snow Leopard installation.  I've copied the AppleUSBVideoSupport file into a folder inside /media but when i try to extract I receive this error message:

$ ift-extract -a /media/macosx/AppleUSBVideoSupport
** (ift-extract:3654): WARNING **: Unknown driver. Please report it to https://bugs.launchpad.net/isight-firmware-tools/+filebug with machine description and Mac OS X version.

** ERROR **: Unable to find firmware in the file.
