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.
