udbp - USB Double Bulk Pipe driver


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.conf5:



The 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 module.


options NETGRAPH
device udbp

Add the driver to the kernel.

kldload netgraph
kldload udbp

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

ngctl mkpeer udbp0: iface data inet
ifconfig ng0

Create a new network interface node and connect its inet hook to the data hook of the node. ifconfig(8) configures the resulting network interface ng0 with a local IP address of and a remote IP address of On the remote host, the two IP addresses should of course be reversed.


netgraph(4), ng_iface4, ohci(4), uhci(4), usb(4), ngctl(8)


The driver first appeared in Fx 5.0 .
