Hi there, I'm new to IOKit development and try my best to get on it. I already had a test driver to work correctly. I've checked "http://developer.apple.com/library/mac/#documentation/Darwin/Conceptual/KEXTConcept/KEXTConceptDebugger/debug_tutorial.html#//apple_ref/doc/uid/20002367-CHDIHFDI" to create the sample driver and use it. Here rises my first problem, although from the link above the IOProviderClass is IOResources, I can't match it with IOServiceMatching dictionary with IOResources as parameter. All I get is the IOResources object itself. If I cahnge the parameter to the class name of my test driver, I get nothing. Is there something wrong here ? If I understand well, only nubs can be matched, correct me if I'm wrong. Therefore how to tell the system that my driver will publish a nub ? If there is any documentation that I couldn't find, I would be glad to get a link. My second problem, is the finality of what I want to do. I have an USB device that acts as a "special" Mass Storage device, it conforms to the Bulk-Only USB Mass Storage specifications and the Mass Storage interface is retained automatically by the IOUSBMassStorageClass driver. Here I want to send some special block to that interface to switch it to another mode but due to the fact that the IOUSBMassStorageClass is retaining the interface, I can't send open the interface from the user mode client. Is there any way to tell the interface client to release the interface from the user land ? I have a workaround to this, just unloading the class IOUSBMassStorageClass from the command line does the trick, but I don't want to unload all the USB Mass Storage devices, only the one I will be using. I have the idea to subclass the IOUSBInterface class and create a new driver that gives a new user interface that gives me the possibility to get down the driver that holds the usb interface, but think it isn't a good idea. And that's why I have the first problem. Thank you for your time in advance. -- "I need a woman who can say, 'honey, can you please take a look at this stack trace while I order the pizza?' and really mean it."
