[Nut-upsdev] Adding device: EitanVT650 to udev nut-usbups.rules?

  I have a UPS device that seems to work fine with the blazer_usb driver.
(I have guessed the driver by googling up the "Product" usb string 010937).
  However, it does not appear in the supported list, and I had to 
manually add a udev rule for granting access to the 'nut' user.

  Would be nice if the info I provide below could be used to help the 
project/future users to have a quicker setup process :-)

   This is the udev rule that seemed to work for me:

#  Eitan VT650 - blazer_usb
ATTR{idVendor}=="ffff", ATTR{idProduct}=="0000",ATTR{product}=="010937", 
MODE="664", GROUP="nut"

(I added the "product" filter, since the idVendor/idProduct info seem to 
have generic values).

I'm using the Debian-unstable package: 2.6.1-2

The specs of the product can be found at:

Following is some info from lsusb -v:
