Before any bulk endpoints are used, the userland-driver does USBDeviceOpen(), GetNumberOfConfigurations(), GetConfigurationDescriptorPtr(), SetConfiguration(), CreateInterfaceInterface(), USBInterfaceOpen() and ResetPipes() with a subsequent DeviceRequest() (with bRequest = kUSBRqClearFeature and wValue = kUSBFeatureEndpointStall) to synchronize the data-toggle.

I've heard on some OSs you need to do this for reasons which are not clear to me, as far as I know its not necessary on Mac OS. -- Barry Twycross email@hidden --- USB, it's not a Dyslexic BUS.
