Function teensy4_bsp::usb::init

pub fn init(
    inst: Instance, 
    config: LoggingConfig
) -> Result<(Poller, Reader), Error>

This is supported on crate feature usb-logging only.

Initializes the USB stack. This prepares the logging back-end. Returns a Reader that can read USB serial messages.

To select the default logger behavior, specify Default::default() as the argument for config.

The inst argument must be the imxrt_ral’s USB1 instance. An incorrect instance results in a Error::WrongInstance error.

This may only be called once. If this is not called, we do not initialize the logger, and log messages will not be written to the USB host. Returns a Error::SetLogger if the logging subsystem already has a logger.

See the module-level documentation for an example.
