NAME

     usb_template — USB device side templates

SYNOPSIS

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

           device usb_template

     To load the module at boot time, place the following line in loader.conf(5):

           usb_template_load="YES"

DESCRIPTION

     The usb_template 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 hw.usb.template sysctl and tunable, or by using the usbconfig(8)
     set_template subcommand.  Changing the 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.

     Available templates are:

        Value    Description
        0        USB Mass Storage, see cfumass(4)
        1        CDC Ethernet, see cdce(4)
        2        Media Transfer Protocol (MTP)
        3        USB serial port, see umodem(4)

        5        USB keyboard
        6        USB mouse
        7        USB phone
        8        CDC Ethernet and serial port
        9        USB MIDI
        10       CDC Ethernet, serial port, and storage
        11       CDC Ethernet Emulation Model, see cdceem(4)

SYSCTL VARIABLES

     The following variables are available as both sysctl(8) variables and loader(8) tunables:

     hw.usb.template
             Currently selected template.  Set to -1 to make the device disappear from the USB
             host point of view.

     hw.usb.template_power
             USB bus power consumption in mA at 5V.  Must be between 0 and 500.  Setting to 0
             marks the device as self-powered.  Defaults to 500mA.

     hw.usb.templates.N
             Configuration for template number N.

     hw.usb.templates.N.vendor_id
             16-bit vendor identifier (VID), usually assigned by USB-IF.

     hw.usb.templates.N.product_id
             16-bit product identifier (PID).

     hw.usb.templates.N.manufacturer
             String containing human-readable manufacturer name.

     hw.usb.templates.N.product
             String containing human-readable product name.
