Your best bet for this kind of questions would be the USB list at
http://lists.apple.com.
If the device is a "vendor specific" device (i.e. bDeviceClass==255) then
you would need to create the interfaces. You can do this by issuing a
SetConfiguration() call to the device. As to what configuration #, you
would need to inspect that Device Descriptor for the bNumConfigurationValue.
However, a good bet is "1". After the SetConfiguration(), the interface
will be created.
Good Luck,
