UDBP(4)                FreeBSD Kernel Interfaces Manual                UDBP(4)

NAME
     udbp - USB Double Bulk Pipe driver

SYNOPSIS
     To compile this driver into the kernel, place the following line in your
     kernel configuration file:

           device udbp

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

           udbp_load="YES"

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 remote IP address
     of 10.0.0.2.  On the remote host, the two IP addresses should of course
     be reversed.
