Here's the output of udesc_dump on it.  Right now, using the current
version of libusb (not the version from ports), I can use
usb_interrupt_write(dev, 1, "MK255", 5, 0) to send data to it --- and
the data is sent --- at least lights on the USB hub flash.  If I
replace '1' with anything else, it doesn't accept it.  However, it
doesn't seem to have opened the relays.

I'm also not entirely clear how/when to use usb_interrupt_read()
... as many of the commands listed in the manual return data, but
usb_inerrupt_write() doesn't seem to allow for data to be returned,
but following usb_interrupt_write(), the read will hang.

... so I'm somewhat at a loss, but I also can't find my multitester
... and will be fetching another one tonight.

I'd appreciate any random knowledge anyone can summon on this topic.
