No supported UPS detected
Support for libusb is 'experimental' at best in FreeBSD and depending
on the version you're using, 'unusable'. You may try if adding a small
delay between sending a command and reading back the reply helps (YMMV):

If your UPS also has a serial port available, it is probably more
reliable to use a USB to serial converter (that is supported by the
kernel) than attempting to run a user space program that attempts to
handle USB through libusb.
