[Nut-upsuser] Data stale and Back UPS ES

[Denis Serov]

Hello!

I tried NUT 2.6.5-1 (Windows port) with my APC Back UPS ES. It seems I have
configured NUT properly, nut-scanner found my UPS:

[nutdev1]
        driver = "usbhid-ups"
        port = "auto"
        vendorid = "051D"
        productid = "0002"
        product = "Back-UPS ES 525 FW:851.t3.I USB FW:t3"
        serial = "8B0745R23575  "
        vendor = "American Power Conversion"
        bus = "bus-0"

I see some errors:
1. UPSMON/UPSC tools are returning "data stale":

What should I check to fix ACCESS-DENIED error?

2. UPSHID-UPS fails with output:

attached to the system is not functioning. ]
   3.728407     Can't initialize data from HID UPS

I installed different versions of libusb driver, but no success.

The most interesting thing is that one of previous version (2.6.0-1 or
2.6.1-1) returned real data from UPS. Any ideas?

Thanks,
Denis
