[Nut-upsuser] There is no voltage information

[Jim Klimov]

Thanks.

  Can you please also check (e.g. with ldd `which usbhid-ups`) which
`libusb` variant (1.0 or 0.1) was the 2.7.4 version of the driver running
with?
  I wonder if the two generations of that library got something
differently?..

  The commit I mentioned -
https://github.com/networkupstools/nut/commit/207fed2282 - which added the
exponent checks, was from 2012 and should be in 2.7.4 as well :-\

  Checked: it is -
https://github.com/networkupstools/nut/blob/v2.7.4/drivers/belkin-hid.c#L157-L194

  Are the two tests running on otherwise the same HW/OS setup?

Jim
