[Nut-upsuser] Upsonic PrOffice 650 usb/serial

I recently installed a Upsonic PrOffice 650 UPS, which is a cheap model[1] 
available in Australia. It has a serial and USB port, and comes with a 
note saying WinPower software can be downloaded from [2]. Investigation of 
the software shows it to be Java with native libraries for serial and USB. 
Disassembling various classes reveals it talks at 2400 baud, and has a 
protocol similar to Megatec [3]. I tested this by connecting with minicom 
to the UPS, and got a status from Q1\r and heard it click on T and TL.

So far, so good. I'd like to use the USB interface, but I can't get it to 
work. It appears in dmesg as
hiddev96: USB HID v1.00 Device [Cypress Semiconductor USB to Serial] on usb-0000:00:1d.0-1
howevery cypress_m8 doesn't bind to it and create /dev/ttyUSB0. newhidups 
doesn't recognise it, but I don't think it should because it's a serial 
interface, not a proper USB HID Power device.

What's my next step towards getting this device running with nut?
