[Nut-upsuser] problem_connection_NUT_infosec

[jgoupil]

Hello everybody,
I have an Infosec's UPS and would like to shutdown 
my computer when he's on battery.
My Infosec's UPS is not in the list of supported UPS 
but the driver is the same than megatec's driver 
(This is the same factory with some differences...)
So, here are my configurations :
-- Ubuntu Desktop --
apt-get install nut
OK

UPS connected to ubuntu via USB cable
After connecting my UPS, a new line appears in "lsusb" :
Bus 001 Device 004: ID 0665:5161 Cypress Semiconductor USB to serial

cd /dev/bus/usb
everything in root:nut 660

cd /dev/usb
everything in root:nut 660

vi /etc/nut/nut.conf
MODE=standalone

vi /etc/nut/ups.conf
[infosec]
driver = usbhid-ups
port = auto
desc = "Infosec UPS"

vi /etc/nut/upsd.users

password = root
action = SET
instcmds = ALL
[localhost]
password = localhost
allowfrom = localhost
upsmon master

vi /etc/nut/upsmon.conf

Do you have any idea?
Is my material not supported or is it a configuration's problem ?

Thanks you,
Regards,
