IOUSBDeviceFamily is a kernel-extension for communication of device to the host via the USB cable. This is only an abstract extension. The actual driver implementation is in AppleSynopsysOTG2.

To use setClassCommandCallbacks, you must issue the call asynchronously, and put the callback function in its reference argument, e.g.
void callback(void* refcon, IOReturn result, size_t* arguments) {
...
}
uint64_t refs[3];
refs[1] = (uint64_t) callback;
refs[2] = (uint64_t) refcon;
IOConnectCallAsyncMethod(connection, 8, wakePort, refs, 3, ...);
