with Communication Device Class Ethernet Emulation Model (CDC EEM). The driver supports both the device, and host side operation; there is a new USB template (#11) for the former. This enables communication with virtual USB NIC provided by iLO 5, as found in new HPE Proliant servers.

.Sh SYNOPSIS
|
|
To compile this module into the kernel, place the following line in
|
|
your kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device usb_template"
|
|
.Ed
|
|
.Pp
|
|
To load the module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
usb_template_load="YES"
|
|
.Ed
|
|
.
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
module implements various USB templates that are needed when
|
|
programming an USB device side driver.
|
|
.
|
|
A USB template consists of an USB device descriptor, one or more USB
|
|
configuration descriptors, one or more USB interface descriptors, one
|
|
or more USB endpoint descriptors, USB strings and additional USB
|
|
descriptors.
|
|
.
|
|
USB templates are selected using the
|
|
.Va hw.usb.template
|
|
sysctl and tunable,
|
|
or by using the
|
|
.Xr usbconfig 8
|
|
.Cm set_template
|
|
subcommand.
|
|
Changing the
|
|
.Va hw.usb.template
|
|
sysctl triggers reenumeration by the USB host; changes to other sysctls
|
|
may not be visible to the host until reenumeration is performed.
|
|
.Pp
|
|
Available templates are:
|
|
.Bl -column -offset 3n "Value"

|
tunables:
|
|
.Bl -tag -width indent
|
|
.It Va hw.usb.template
|
|
Currently selected template.
|
|
Set to -1 to make the device disappear from the USB host point of view.
|
|
.It Va hw.usb.template_power
|
|

Defaults to 500mA.
|
|
.It Va hw.usb.templates.N
|
|
Configuration for template number
|
|
.Va N .
|
|
.It Va hw.usb.templates.N.vendor_id
|
|
16-bit vendor identifier (VID), usually assigned by USB-IF.
|
|
.It Va hw.usb.templates.N.product_id
|
|
16-bit product identifier (PID).
|
|
.It Va hw.usb.templates.N.manufacturer
|
|
String containing human-readable manufacturer name.
