Hi,

I repeat several months after: The patch from Brian R. Smith WORKS!

I can't understand why the main developers of NUTS don't like to add support to 
this protocol! SEVERAL UPS units in the world (very inexpensive hardware) uses 
the same hardware: vendorid = 0001, productid = 0000; with a MODIFIED blazer_usb 
protocol.

All this hardware uses the infamous UPSlion 2000 Software and NO TOHER SOFTWARE 
ALTERNATIVES EXISTS.

PLEASE! PLEASE! PLEASE! Add support for it!
Several people has created patches, and no one likes to merge it with de main 
branch of the NUT.

Creazy!
