.Dd April 30, 2000 .Dt UDBP 4 .Os FreeBSD .Sh NAME .Nm udbp .Nd USB Double Bulk Pipe driver .Sh SYNOPSIS .Cd "device udbp" .Sh DESCRIPTION The .Nm driver provides support for host-to-host cables that contain at least two bulk pipes, one for each direction, like for example the EzLink cable and the NetChip 1080 chip.
p It requires netgraph to be avalable. This can be done either by adding .Cd "options NETGRAPH" to your kernel configuration file, or alternatively loading .Nm netgraph as a module either from
a /boot/loader.conf or from the command line, before the udbp module. .Sh EXAMPLE .Dl options NETGRAPH .Dl device udbp
p Add the .Nm udbp driver to the kernel.
p .Dl kldload netgraph .Dl kldload udbp
p Load the .Nm netgraph module and then the .Nm udbp driver.
p .Dl ngctl mkpeer udbp0: iface data inet .Dl ifconfig ng0 10.0.0.1 10.0.0.2
p Create a new network interface node node and connect it's inet hook to the data hook of the .Nm udbp node. Ifconfig configures the resulting network interface ng0 with a local IP address of 10.0.0.1 and a remote 10.0.0.2. On the remote host the two IP addresses should of course be reversed.
