USB_BUS_START_ENUM(9) Host Controller APIs USB_BUS_START_ENUM(9)NAME
usb_bus_start_enum - start immediate enumeration (for OTG)
int usb_bus_start_enum(struct usb_bus * bus, unsigned port_num);
the bus (must use hcd framework)
1-based number of port; usually bus->otg_port
Starts enumeration, with an immediate reset followed later by khubd 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.
0 if successful.

FIREWIRE(4) BSD Kernel Interfaces Manual FIREWIRE(4)NAME
firewire -- IEEE1394 High-performance Serial Bus
To compile this driver into the kernel, place the following line in your kernel configuration file:
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
FreeBSD provides machine-independent bus support and raw drivers for firewire interfaces.
The firewire driver consists of two layers: the controller and the bus layer. The controller attaches to a physical bus (like pci(4)). The
firewire bus attaches to the controller. Additional drivers can be attached to the bus.
Up to 63 devices, including the host itself, can be attached to a firewire bus. The root node is dynamically assigned with a PHY device
function. Also, the other firewire bus specific parameters, e.g., node ID, cycle master, isochronous resource manager and bus manager, are
dynamically assigned, after bus reset is initiated. On the firewire bus, every device is identified by an EUI 64 address.
SEE ALSO fwe(4), fwip(4), fwohci(4), pci(4), sbp(4), eui64(5), fwcontrol(8), kldload(8), sysctl(8)HISTORY
The firewire driver first appeared in FreeBSD 5.0.
The firewire driver was written by Katsushi Kobayashi and Hidetoshi Shimokawa for the FreeBSD project.
