Charles is right in both the fact that the issue is (or at least seems to
be) upstream to NUT, and also that it's worth checking with "Eaton"

Could you please tell me your kernel and libusb (0.1) version?

Would you also be able to test some github code?
We have the libusb-1.0 branch that provides both libusb 1.0 support
(interesting to test to see if the problem still happens) along with few
other improvements (though these should not help for your issue):

Don't hesitate if you need more guidance for trying this branch.

FYI, I've just made a test with the same unit, on a Debian jessie (kernel
3.16.43-2, libusb 0.1.12-25) both with 2.7.4 and the latest git master, and
it works fine:
