7.8 Set Feature Request
Set Feature request is just the opposite of Clear Feature request. If the recipient is a device, then MCU will need
to set the device's feature according to the feature selector on the setup packet. Again, there is no support for the
Interface recipient. For example, if the feature selector is 0 (which means enabling endpoint), the D12 specific
endpoint will have to be stalled through "D12_SetEndpoint status" command.
