	Yes.  You can select one of following selection.

1. to use usb module.
   echo 'usb_load="YES"' >> /boot/loader.conf.local
   Remove 'device usb' / 'device uhci' / 'device ohci' from your kernel
   configuration.

2. to use device usb.
   Don't echo 'usb_load="YES"' >> /boot/loader.conf.local
   Add 'device usb' and ('device uhci' or/and 'device ohci') to your kernel
   configuration.
