NAME

       usb_quirk — USB quirks module

SYNOPSIS

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

             device usb_quirk

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

             usb_quirk_load="YES"
