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 ?
