Nut upsuser - Jul 2017 - INFOSEC X4 not supported by blazer_usb

Hello,

I  am trying to make my UPS system working with NUT but with no success. 
I got "No supported UPS detected" message.

I use the blazer_usb driver since it was proposed to me by the web site.
My NUT version is : 2.7.1 (installed from standard RPM), release 2.41

The UPS identification:
INFOSEC X4 RM PLUS

linux-2qya:~ # /usr/lib/ups/driver/blazer_usb -a infosec
Network UPS Tools - Megatec/Q1 protocol USB driver 0.10 (2.7.1)

linux-2qya:~ # tail -13 /etc/ups/ups.conf

Thanks in advance for any tips you could propose.

What's the output of the 'blazer_usb' driver launched with a debug
level of 3 (i.e. `/usr/lib/ups/driver/blazer_usb -DDD -a infosec`)?
Also, can you, please, try the 'nutdrv_qx' driver?
