Struct BusController 

pub struct BusController<'d, C: UsbHostController<'d>> { /* private fields */ }

Bus-level controller for a single root USB controller.

Owns the UsbHostController implementation and exposes the bus-wide operations that must be serialised against each other (root-port event waiting, bus reset).

Pipe allocation and device enumeration live on the companion BusHandle returned alongside a BusController by the bus constructor.

Implementations

impl<'d, C: UsbHostController<'d>> BusController<'d, C>

pub fn controller(&self) -> &C

Get a reference to the underlying controller.

pub fn controller_mut(&mut self) -> &mut C

Get a mutable reference to the underlying controller.

pub async fn wait_for_device_event(&mut self) -> DeviceEvent

Wait for a root-port attach/detach.

On attach, the implementation drives a bus reset to completion before returning and reports the speed the device settled on.

pub async fn wait_for_connection(&mut self) -> Speed

Wait for a device to connect on the root port.

Issues a bus reset internally and returns the detected speed. Spurious disconnects, overcurrent events, and other non-attach events are silently absorbed.
