USB_BUS_START_ENUM(9)                  Host Controller APIs                 USB_BUS_START_ENUM(9)



NAME
       usb_bus_start_enum - start immediate enumeration (for OTG)

SYNOPSIS
       int usb_bus_start_enum(struct usb_bus * bus, unsigned port_num);

ARGUMENTS
       bus
           the bus (must use hcd framework)

       port_num
           1-based number of port; usually bus->otg_port

CONTEXT
       in_interrupt

DESCRIPTION
       Starts enumeration, with an immediate reset followed later by hub_wq identifying and
       possibly configuring the device. This is needed by OTG controller drivers, where it helps
       meet HNP protocol timing requirements for starting a port reset.

RETURN
       0 if successful.
