1 Finding the Apple driver

ift-extract extract Built-in iSight firmware from Apple iSight driver. This driver is located at /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBVideoSupport.kext/Contents/MacOS/AppleUSBVideoSupport on your Mac OS X root partition.

There is several version of this driver depending on driver version or host architecture (PowerPC or x86). Thus, ift-extract must determine know the variant of the driver in order to properly extract the firmware.

Any AppleUSBVideoSupport file starting with those shipped with iMac G5 iSight must work. If not, please report unknown AppleUSBVideoSupport at bugreport mail address with machine type and OS X version.

2 Command line options

`-a' `--apple-driver' Apple driver filename where to extract the firmware.

`-d' `--output-directory' The directory where to output the firmware. Defaults to /lib/firmware.

`-f' `--output-filename' The output firmware name. Defaults to isight.fw

`-?' `--help' Shows option help and quit.

Since ift-extract defaults to output the firmware to /lib/firmware/isight.fw, ensure you have the right to do so.
