Represents a USB HID device with state tracking

Fields

address: u8

USB device address on the bus

interface: u8

Interface number within the USB configuration

device_type: HidDeviceType

Detected device type

interrupt_endpoint: u8

Interrupt IN endpoint address (for polling reports)

poll_interval_ms: u8

Interrupt endpoint polling interval in milliseconds

max_packet_size: u16

Maximum packet size for the interrupt endpoint

boot_protocol: bool

Whether the device is in boot protocol mode

capabilities: HidCapabilities

Parsed device capabilities

Implementations

impl HidDevice

pub fn new_boot_keyboard( address: u8, interface: u8, endpoint: u8, interval: u8, ) -> Self

Create a new HID device with boot protocol configuration

pub fn new_boot_mouse( address: u8, interface: u8, endpoint: u8, interval: u8, ) -> Self

Create a new HID device configured as a boot mouse

pub fn from_capabilities( address: u8, interface: u8, endpoint: u8, interval: u8, caps: HidCapabilities, ) -> Self

Create a HID device from parsed capabilities

pub fn submit_report(&mut self, data: &[u8]) -> Result<(), KernelError>

Submit report data received from an interrupt transfer.

Stores the data in the internal buffer for subsequent process_report calls.

pub fn process_report(&mut self) -> Result<InputEventBatch, KernelError>

Process the current report buffer and generate input events.

Returns a small array of events. For keyboards this includes key press/release deltas compared to the previous report; for mice this includes movement, button changes, and scroll.

pub fn poll_device(&mut self) -> Option<InputEvent>

Poll the device for new input (stub).

In a real implementation this would issue an interrupt transfer to the device’s interrupt IN endpoint via the host controller and return the first event from the resulting report. This stub always returns None.

Trait Implementations

impl Debug for HidDevice

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
