[Nut-upsdev] Krauler UP-M500VA investigation

[Alexander I. Gordeev]

Hi, All!

I've recently bought an UPS. It is Krauler UP-M500VA, it has USB
port and is a HID device.

But as I discovered the only HID application it supports is 0x860004,
so it isn't claimed by both hidups and newhidups drivers, because it
uses a vendor-specific values. I tried to discover values in that x86
page, but I failed. How can I do it?

And after I get values how to understand what they mean? I've seen
this comment in hidups.c:

        /* results of querying some x86 page values on my APC UPS */

        /* note to APC: i can decode your "secret protocol" just by        *
         * looking at it.  you're not helping anyone by keeping it closed! */

Maybe this person who wrote this lines could look at my values to? :)
