Set Interface (Request Code 11)

This request allows the host to select an alternate setting for the specified interface.
Some USB devices have configurations with interfaces that have mutually exclusive settings. This request
allows the host to select the desired alternate setting. If a device only supports a default setting for the
specified interface, then a STALL may be returned in the Status stage of the request. This request cannot be
used to change the set of configured interfaces (the SetConfiguration() request must be used instead).
If the interface or the alternate setting does not exist, then the device responds with a Request Error. If
wLength is non-zero, then the behavior of the device is not specified.
Default state: Device behavior when this request is received while the device is in the Default state is not
specified
.
Address state: The device must respond with a Request Error.
Configured state: This is a valid request when the device is in the Configured state.
