What does your tw.com.MyCompany.kext.MyKext bundle do? You must have a
IOClass called "MyKEXT"? What methods does it implement?
Also, what is the % ioreg output when your device is plugged in? Something
like:
| | +-o Microsoft 5-Button Mouse with IntelliEye(TM)@2122000
<class IOUSBDevice>
| | | +-o AppleUSBComposite <class AppleUSBComposite>
| | | +-o IOUSBInterface@0 <class IOUSBInterface>
| | | | +-o IOUSBHIDDriver <class IOUSBHIDDriver>
| | | | | +-o IOHIDPointing <class IOHIDPointing>
| | | | | | +-o IOHIDSystem <class IOHIDSystem>
| | | | | | +-o IOHIDParamUserClient <class
IOHIDParamUserClient>
| | | | | | +-o IOHIDUserClient <class IOHIDUserClient>
| | | | | +-o IOHIDLibUserClientIniter <class
IOHIDLibUserClientIniter>
| | | | +-o IOUSBUserClientInit <class IOUSBUserClientInit>
| | | | +-o IOUSBInterfaceUserClient <class
IOUSBInterfaceUserClient>
| | | | +-o IOUSBInterfaceUserClient <class
IOUSBInterfaceUserClient>
| | | +-o IOUSBUserClientInit <class IOUSBUserClientInit>
(i.e. Just send the part corresponding to your device and any interfaces it
has).
