You mention compiling against libusb-1.0 but do not mention which NUT codebase you use. The master branch at the moment does not support it, only libusb-0.1 and there are some known connectivity stability bugs associated with that.

Currently there is a long-pending competition of several implementations, neither of which were merged yet since respective change authors did not consider their work perfect enough:

https://github.com/networkupstools/nut/issues/300

https://github.com/networkupstools/nut/tree/libusb-1.0

https://github.com/networkupstools/nut/tree/libusb-1.0%2B0.1

https://github.com/networkupstools/nut/tree/libusb-compat-1.0

I believe you should pick whichever works for you (please report on those which do not work and how, if any), sync with current master should be possible for all of them.

Hope this helps,
Jim Klimov
