Hello,

I'm working on an installer that, among other things, installs a kext for an IOKit driver. I've got it working in an installer that requires a reboot - the kext gets installed correctly and the kext cache gets rebuilt. However, I'm wondering if there's a way to do this without requiring a reboot. This installer requires 10.6 or later, so I don't have to concern myself with older versions of OS X. And if it matters, the driver doesn't actually do anything - it's a stub to prevent the default USB driver from being used. A separate daemon handles communication with the device.

Unfortunately, in my googling so far I haven't found a clear answer. I've read this document: http://developer.apple.com/library/mac/#qa/qa1319/_index.html but I don't quite follow it. Is it saying that if I'm installing an IOKit kext in 10.5 or newer, I don't have to do anything other than executing `touch /System/Library/Extensions`?

And probably loading the kext with kextload from the postinstall script.

I just gave it a try, and it almost works. After running the installer without a reboot, unplugging and plugging back in my USB device will have it load with the correct driver. In this case it doesn't matter whether or not I call kextload. So the question is: how can I force OS X to update which driver its using for a device without requiring the user to unplug and plug it back in manually? - Brian _______________________________________________ Do not post admin requests to the list.
