The USB Class driver for your device is taking control of the interfaces. If you want it not to do that, you will have to write code-less kexts that match to the interfaces with a higher probe score than the class driver. This has been discussed in the past

had a question about when a phone is connected to the comp. i'm trying to write a simple program where it can send/receive data to the phone via usb and i've modified the usb simple example to find the ports of the phone that i plug in. but when i try to open the device, i get the kIOReturnExclusiveAccess error everytime. i went into the system preferences and i saw that it configured it as a network port. i guess cos the phone is a communications device? but i unchecked them, but they're still there. so my question is, is this what's opening the device as soon as i plug the phone in? or is there some other task that keeps it open? thanks everyone!
