[Nut-upsuser] Tecnoware ERA LCD (UPSilon 2000) communication problem

[Rob Power]

Hi to everyone!

I'm posting here after digging around the nut-upsuser and nut-upsdev
mailing list, hoping I didn't miss something important.

I'm trying to make my ups working with nut: it's a Tecnoware ERA LCD 0.85
which uses the so-hated UPSilon 2000 software to connect via usb.

Personally I checked and seems that this junk software only works from
windows, I'm trying to contact with tecnoware to get some info.
I read a lot in the mailing-list about the "langid_fix" patch that seems
was definitively included in released 2.6.3.

HCL suggest "blazer_usb langid_fix=0x4095" for a similar product but it
seems to not work.
Here are my settings, I attached the debug output of blazer_usb start.
Nut version is stable 2.6.5.
Does anyone has any suggestions please?

[ERA_LCD]
     driver = blazer_usb
     subdriver = krauler
     langid_fix=0x4095
     port = /dev/bus/usb/002/002
     vendorid = 0001
     productid = 0000
     desc = "Tecnoware UPS ERA 0.8"

port was setted according to lsusb output:
$ lsusb
[...]
Bus 002 Device 002: ID 0001:0000 Fry's Electronics

Thanks in advance for any help.
Greetings,
Rob
