* <b>FEATURELESS_CONTROL_ONLY_DEVICE</b> \n
* In some limited USB device applications, device features (other than self-power) and endpoints other than the control endpoint aren't

* parts of the Get Feature chapter 9 request to save space. Generally, this is usually only useful in (some) bootloaders and is best avoided.
* <b>CONTROL_ONLY_DEVICE</b> \n
* In some limited USB device applications, there are no device endpoints other than the control endpoint; i.e. all device communication
