Problems with USB matching an EZ-USB based USB device!

Hi all,

i have a device that uses a EZ-USB chip. When my driver loads, he checks if the product-id is the unenumerated device, uploads the code and closes the device. If the product-id is the enumerated device he just goes further with normal driver process. If i test my driver with just kextload and kextunload mac os x always matches my driver no matter if my device is in a enumerated state or not. The problem ocurrs in the deployment version. When my kext is installed in /System/Extensions/ it only gets loaded at startup if the device is in a unenumerated status. If I boot my computer and the device attached ( during startup ) is already enumerated my driver never gets loaded, unless i disconnect and connect the usb-cable from the computer ( sometime after boot process ). Why doesn't mac os x match my enumerated driver at startup by itself?

I suspect it has something to do with my wierd looking Info.plist file. I used the trick to have two IOKitPersonalities. Here's a copy ( names changed, comments added ):
