[Nut-upsuser] No matching HID UPS found

[jfmxl at sdf.org]

Hello,

Network UPS Tools - Generic HID driver 0.38 (2.7.2)
USB communication driver 0.32
No matching HID UPS found
Driver failed to start (exit status=1)

I followed a thread with the same title, more or less, having permission 
problems. I applied that solution. My problem seems different.

# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 010: ID 0665:5161 Cypress Semiconductor USB to Serial
Bus 002 Device 003: ID 046d:c31c Logitech, Inc. Keyboard K120 for 
Business
Bus 002 Device 002: ID 1c4f:0065 SiGma Micro
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

When I unplug the USB cable from my Easton 5L 600VA USB

# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 003: ID 046d:c31c Logitech, Inc. Keyboard K120 for 
Business
Bus 002 Device 002: ID 1c4f:0065 SiGma Micro
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

So, apparently, my Easton is sending

Bus 002 Device 010: ID 0665:5161 Cypress Semiconductor USB to Serial

The other examples show Eastons sending stuff like ...

Bus 003 Device 002: ID 0463:ffff MGE UPS Systems UPS

When I run

# upsdrvctl start easton
Network UPS Tools - UPS driver controller 2.7.2
Network UPS Tools - Generic HID driver 0.38 (2.7.2)
USB communication driver 0.32
No matching HID UPS found
Driver failed to start (exit status=1)

The contents of my /etc/nut/ups.conf

maxretry = 3
[easton]
driver = usbhid-ups
port = auto
desc = "Eaton 5L 600"

and of /etc/udev/rules.d/90-nut-ups.rules

# Eaton 5L 600
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="0665", 
ATTR{idProduct}=="5161", MODE="0660", GROUP="nut"

Any clues as to what's wrong?

I initially tried Easton's software ... with more or less the same 
result : searched endlessly for the UPS device.
