udbp(4)

NAME

udbp - USB Double Bulk Pipe driver

SYNOPSIS

device udbp

DESCRIPTION

The udbp driver provides support for host-to-host cables

that contain at
least two bulk pipes (one for each direction), for example

the EzLink
cable and the NetChip 1080 chip.

It requires netgraph(4) to be available. This can be done

either by
adding options NETGRAPH to your kernel configuration file,

or alternatively loading netgraph(4) as a module, either from

/boot/loader.conf or
from the command line, before the udbp module.

EXAMPLES

options NETGRAPH
device udbp

Add the udbp driver to the kernel.

kldload netgraph
kldload udbp

Load the netgraph(4) module and then the udbp driver.

ngctl mkpeer udbp0: iface data inet
ifconfig ng0 10.0.0.1 10.0.0.2

Create a new network interface node and connect its inet

hook to the data
hook of the udbp node. ifconfig(8) configures the resulting

network
interface ng0 with a local IP address of 10.0.0.1 and a re

mote IP address
of 10.0.0.2. On the remote host, the two IP addresses

should of course
be reversed.
