class ControlTransfer

Defined at line 217 of file fidling/gen/sdk/fidl/fuchsia.hardware.usb/fuchsia.hardware.usb/cpp/fidl/fuchsia.hardware.usb/cpp/markers.h

Performs a synchronous USB control transfer (IN or OUT) over endpoint 0.

Replies after the control transaction completes on the bus (and any associated host

controller state updates for standard `SET_CONFIGURATION` or `SET_INTERFACE` requests

finish).

While this method can be used to read descriptors, prefer [`GetDeviceDescriptor`] and

[`GetConfigurationDescriptor`] when reading descriptors.

If `timeout_ns` is 0 or negative, a default 5-second timeout is used (per USB 2.0

Section 9.2.6.4).

* error:

* `ZX_ERR_INVALID_ARGS` if the setup packet length or `write_data` size is invalid.

* `ZX_ERR_TIMED_OUT` if the control transfer does not complete within the timeout.

* `ZX_ERR_IO_REFUSED` if the device returns a STALL handshake.

* `ZX_ERR_IO_NOT_PRESENT` if the device has been disconnected.

* `ZX_ERR_NOT_SUPPORTED` if the server does not support raw control transfers.
