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.
