Hi,

I finally got something. I followed B.J. Buchalter sugestion and attached a custom executable (MIDI server at the frameworks) in Xcode to the sample driver project.

After running the output was something like:

device @ 0xFD400000 - can't get descriptor

Well, after some look around in the USBDevice.cpp file, i couldnt find any reference to a particular product/vendor ID. I can only see that in the SampleUSBDriver.cpp, but i also could see that it never reaches that point.

- Where is defined the device that the driver will match?

Because, as i could see, the first function that is called in the driver is the GetDeviceDescriptor and i couldnt find any other place that calls this function, at least in this same file.

Can anyone give me a light here?

Thx,

Nuno
