Since a perlish solution was requested:
Code:
$\ = "\n";
$, = '';

while (<>) {
    chomp;

    if (my ($usb, $word) = m{^(USB\w+)\s+(.*)$}) {
        $U{$usb} = $word;
        next;
    }

    if (my ($usb, $word) = m{^START_PATH\s+(USB\w+)(\..*)$}) {
        $U{$usb} ||= '<undef>' unless defined $U{$usb};
        print $U{$usb}, $word;
    }
}

usb_template

USB_TEMPLATE(4) 					   BSD Kernel Interfaces Manual 					   USB_TEMPLATE(4)

NAME

     usb_template -- USB 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.  The USB template module currently has templates for USB Mass Storage, USB CDC Eth-
     ernet and Message Transfer Protocol.  USB templates are currently selected using the "hw.usb.template" sysctl.  The "hw.usb.template" value
     can be changed at any time, but will not have any effect until the USB device has been re-enumerated.

SEE ALSO

     usb(4)

STANDARDS

     The usb_template module complies to the USB 1.0, 2.0 and 3.0 standard.

HISTORY

     The usb_template module was written by Hans Petter Selasky <hselasky@FreeBSD.org>.
