Ok,

Then you have to recompile apcupsd to use the generic USB driver (NOT the 
bsd.c). Maybe you can figure this out?

/usr/ports/sysutils/apcupsd/work/apcupsd-3.14.4/src/drivers/usb/generic
Makefile        generic-usb.c   hidutils.c      hidutils.h      libusb.h.in

After that libusb gets installed you can use libmap.conf to make apcupsd use 
libusb20 instead of libusb from ports.
