Kext is working great for me, well done and thanks. The only issue I have is that my device has volume controls on the keyboard, but also hardware volume control keys on the side. The keyboard volume keys work OTB, but I am having difficulty figuring out what scan codes to send for the ACPI volume keys. I've tried all the "standard" PS2 codes I can find without success. Does anyone which codes to use? I know the problem isn't my ACPI methods, just for kicks I set them to send the brightness controls and that works fine. Thanks is advance!
