First of all, it appears to me that you don't really need a driver

your needs for you.
It's close to the same thing except I don't need to examine power
states, but I provide for firmware updates, and it has to connect to
my main DMX controller in-kernel, and it needs to remove itself from
control by the HID Manager! I must capture the device and interface
for my driver's exclusive use.
Well, the IOUSBHIDDriver does not do anything with the IOUSBDevice
object, so that shouldn't be an issue. Also, even though the
AppleUSBComposite driver is driving that object, it doesn't leave it
open(), and so it isn't a problem either.
As far as the IOUSBInterface driver goes, is there a difference
between when the device is plugged in at boot time and when it is
plugged in after boot? This may be a problem with the IOUSBHIDDriver
being a higher priority at boot time.
It matches IOUSBHIDDriver every time. Maybe my IOProviderClass is
wrong?
Well, I don't see any obvious errors in the personality that you sent.
Are you sure that your DurandDMX4201USBInterface::start method is not
getting called? Perhaps it is getting called and it is returning false?
Are you sure that your kext is actually able to load? The following
should verify that:
% sudo kextload -v DurandDMX4201USBInterface.kext
