The changes were apparently going to appear in a release after 10.3.6,
but it seems that this is still not the case.
Are you sure? The fix went out in 10.3.8. You can download the
logging version of the IOUSBFamily and capture a level 6 log. Then go
to http://bugreporter.apple.com and file a bug. Then let us know the
bug # so we can take a look.
I have nailed down to where the problem in the IOKit is occuring, in
IOUSBDeviceClass and want to override that method to handle the case
for my device. I can't for the life of me figure out how to do this.
Is it possible for an IOUSBDevice to return a custom IOUSBDeviceClass?
The IOKit fundamentals doesn't seem to make a mention of what a device
class is exactly and how it interacts with the device. It would be
easy if an IOUSBDevice could return the device class as I could just
return the patched up method in a subclass.
Does anyone have any advice on how to go about this? Is it possible to
patch that method in IOUSBDeviceClass without having to make a
subclass?
This is something that is not recommended. I don't even know if it's
possible or not.
