Struct UsbHost 

pub struct UsbHost<'d, D: UsbHostDriver<'d>> { /* private fields */ }

USB host controller.

Manages device connection, enumeration, and class driver binding.

Implementations

impl<'d, D: UsbHostDriver<'d>> UsbHost<'d, D>

pub fn new(driver: D) -> Self

Create a new USB host from a driver.

pub fn free_address(&mut self, addr: u8)

Release a previously allocated device address.

pub fn driver(&self) -> &D

Get a reference to the underlying driver.

pub fn driver_mut(&mut self) -> &mut D

Get a mutable reference to the underlying driver.

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

Wait for a device to connect.

Issues a bus reset internally and returns the detected speed.

pub async fn enumerate( &mut self, route: BusRoute, config_buf: &mut [u8], ) -> Result<(EnumerationInfo, usize), EnumerationError>

Enumerate a connected device.

Performs the standard enumeration sequence:

1. Get device descriptor (first 8 bytes) to learn EP0 max packet size
2. SET_ADDRESS to assign a unique address
3. Get full device descriptor
4. Get configuration descriptor
5. SET_CONFIGURATION

route describes how the device is reached on the bus (directly at its native speed, or via split transactions / legacy PRE through a hub’s transaction translator).

Preconditions

The caller must have placed the device into the default (address 0) state before calling this method. For a root-port device that means an upstream bus reset has completed; for a hub-attached device, the parent hub’s port reset must have completed and BusRoute::Translated must carry the appropriate SplitInfo.

Returns the EnumerationInfo for the device and bytes written to config_buf.
