Re: IOUSBHIDDriver, Tiger vs Panther



Your Panther-built IOUSBHIDDriver-based kext should work on Tiger. If it's not, it is a bug in our stuff. I will test this and report back, although I find it difficult to believe, as it is something that we test.

A Tiger-built IOUSBHIDDriver-based kext will never work on Panther. We guarantee forward binary compatibility, but not backwards binary compatibility.

I have a IOUSBHIDDriver-based mouse driver. Apparently the IOUSBHIDDriver
class changed such that a driver built on Panther will not work on Tiger and
vice-versa (I get the "not compatible with its superclass" error when trying
to load). My question is, am I stuck with 2 different drivers or is there a
way to build a driver that will be compatible on both?
