are two supported chips, the NetChip 1080 (only prototypes available) and the EzLink cable. Any other cable should be supported however as they are all very much alike (there is a difference between them wrt performance). It uses Netgraph. This driver was mostly written by Doug Ambrisko and Julian Elischer and I would like to thank Whistle for yet another contribution. And my aplogies to them for me sitting on the driver for so long (2 months). Also, many thanks to Reid Augustin from NetChip for providing me with a prototype of their 1080 chip. Be aware of the fact that this driver is very immature and has only been tested very lightly. If someone feels like learning about Netgraph however this is an excellent driver to start playing with.

.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.
|
|
.Pp
|
|
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
|
|
.Pa /boot/loader.conf
|
|
or from the command line, before the udbp module.
|
|
.Sh EXAMPLE
|
|
.Dl options NETGRAPH
|
|
.Dl device udbp
|
|
.Pp
|
|
Add the
|
|
.Nm udbp
|
|
driver to the kernel.
|
|
.Pp
|
|
.Dl kldload netgraph
|
|
.Dl kldload udbp
|
|
.Pp
|
|
Load the
|
|
.Nm netgraph
|
|
module and then the
|
|
.Nm udbp
|
|
driver.
|
|
.Pp
|
|
.Dl ngctl mkpeer udbp0: iface data inet
|
|
.Dl ifconfig ng0 10.0.0.1 10.0.0.2
|
|
.Pp
|
|
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.
