Fintek USB serial UART module?

I've got this Protectli device with Pfsense (FreeBSD 14.0) installed. I was hoping to use it to access the serial port of its HA pair for offline maintenance. When I plug it in ugen0.2 appears, but there's no cuaU* or ttyU* device present in /dev.

Code:
$ usbconfig list
ugen0.1: <Intel XHCI root HUB> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=SAVE (0mA)
ugen0.2: <FINTEK USB TO UART BRIDGE> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA)

In my experience, this usually indicates that there's no matching kernel module installed. The Fintek website lists only linux and windows source to build the drivers which doesn't seem promising. Is there anything I can do to get this to work as-is or am I out of luck with this UART?
 
I have a similar device and a cuaU* will be created when plugged in. Afaik these 3 modules are involved: uplcom.ko, ucom.ko and cuse.ko. In /boot/loader.conf I have cuse_load="YES".
