class Control

Defined at line 428 of file fidling/gen/sdk/fidl/fuchsia.hardware.usb.dci/fuchsia.hardware.usb.dci/cpp/fidl/fuchsia.hardware.usb.dci/cpp/markers.h

Dispatch a control transaction (EP0 SETUP transfer).

See usb20 8.5.3 (Control Transfers) and 9.6 (Standard Device Requests).

Only called by DCI while the controller is running, after a SETUP packet is received on EP0.

This method replies after the peripheral controller or the target function driver has

processed the request.

To comply with USB 2.0 Section 9.2.6 (Request Processing Timing), the peripheral driver must

process and reply to requests without a data stage (and `SET_ADDRESS`) within 50 ms. For

requests with a data stage, it must reply (beginning the data stage) within 500 ms. Both

drivers must process these requests within these limits to prevent host-side timeouts and

enumeration failures.

* error:

* `ZX_ERR_NOT_SUPPORTED` if the request is not recognized.

* `ZX_ERR_BAD_STATE` if called while the controller is stopped or interface is not

bound.

Note: For any error returned by this method, the DCI driver stalls EP0 with a `STALL`

handshake to signal the failure to the USB host.
