site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com Attempting to kextload a driver when the above error (see subject line) occurs. Driver consists of the basic HelloIOKit example plus first few lines of AppleUSBComposite::start. Specifically this line: "_device=OSDynamicCast(IOUSBDevice, provider)". When this call is absent the driver loads. When present I get the above error. Somehow kextload doesn't recognize the IOUSBDevice symbol used in OSDynamicCast. At least that's what I gather from the kld() error message. I am including the IOUSBDevice.h header in cpp file. Can anyone shed some light on this ?
