10

ARGUMENTS

12       bus
13           the bus (must use hcd framework)
14
15       port_num
16           1-based number of port; usually bus->otg_port

DESCRIPTION

22       Starts enumeration, with an immediate reset followed later by hub_wq
23       identifying and possibly configuring the device. This is needed by OTG
24       controller drivers, where it helps meet HNP protocol timing
25       requirements for starting a port reset.
26

RETURN

28       0 if successful.
