Struct UsbHotplugManager 

pub struct UsbHotplugManager { /* private fields */ }

USB Hotplug Manager

Tracks port status for up to MAX_PORTS ports and generates attach/detach events by polling PORTSC change bits.

Implementations

impl UsbHotplugManager

pub const fn new() -> Self

Create a new hotplug manager

pub fn init(&mut self, portsc_base: usize, num_ports: u8)

Initialize with the xHCI operational register base and port count

pub fn poll(&mut self)

Poll all ports for status changes

Reads PORTSC registers, detects CSC (Connect Status Change), and generates appropriate events.

pub fn get_event(&mut self) -> Option<UsbHotplugEvent>

Get the next pending hotplug event

pub fn has_events(&self) -> bool

Check if there are pending events

pub fn pending_event_count(&self) -> usize

Get the number of pending events

pub fn register_callback( &mut self, callback: HotplugCallback, ) -> Result<(), KernelError>

Register a callback for hotplug events

pub fn port_status(&self, port: u8) -> Option<&UsbPortStatus>

Get port status for a specific port

pub fn num_ports(&self) -> u8

Get the number of monitored ports

pub fn total_attach_events(&self) -> u32

Get total attach event count

pub fn total_detach_events(&self) -> u32

Get total detach event count

pub fn is_initialized(&self) -> bool

Check if the hotplug manager is initialized
