Pretty much all of the USB-based APC UPSes work with the "usbhid-ups"
driver. "apcsmart" is only used if you connect via the serial port.
(The USB entries are towards the bottom of the APC section of the
compatibility list, so maybe we can make that clearer.)

You won't need the symlink, either - usbhid-ups has parameters to
select an UPS by serial number, vendor ID, etc, and it ignores the
value for "port". Check the man page for more details.
