I don't think so.
the issue reported here was related to a code change, that resulted in a
regression.

yours seem to be with privileges.
to validate this, try launching the driver with root privs (note the "-u
root"):
$ sudo /lib/nut/usbhid-ups -u root -DDDD -a mybelkin

 Is there a fix

it's related to udev, and since there seems to be quite some similar issues,
I'm wondering if there is a race condition between udev (started through
upstart native scripts) and nut (started through upstart sysV compat
script).

cheers,
Arnaud
