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.
