Your mail is mangled.  Lines longer than 72 characters which are
logs/config/output etc. should not be wrapped.

But, I can tell that Debian has old nut.  My system has 2.8.2.  And
there are changes in git master since then.   I'm not the maintainer,
but for projects where I have a maintainer role, I expect the first
step is updating to the latest release if not from git.

It's really hard to say from this.   I would think there is a way to
tell usbhid-ups the device name and have it just try that.    Could be a
debian issue, could be something wrong with nut.   My advice would be to
build git master and debug from there, with gdb and ktrace (however you
spell ktrace on debian, perhaps it is strace).
