class UsbFunction

Defined at line 29 of file ../../src/devices/usb/drivers/usb-peripheral/usb-function.h

This class represents a USB function in the peripheral role configurations.

USB function drivers bind to this.

void SetConfigured (bool configured, usb_speed_t speed, fit::callback<void (zx_status_t)> completer)

If SetConfigured(true, ...) is called from an already configured state,

then a deconfigure/reconfigure sequence is performed to reset the function

state.

TODO(https://fxbug.dev/493657863): This call should be async like

SetConfigured and SetInterface once we can guarantee a single-dispatch of

USB_RECIP_DEVICE requests to bound functions.

std::optional<std::vector<uint8_t>> GetEndpointsForInterface (uint8_t interface_num, uint8_t alt_setting)

Returns all endpoint addresses associated with the given interface and alternate setting

by parsing the function's descriptors. Returns std::nullopt if the function has no descriptors

(e.g. mock test functions).
