The packages built against libusb-1.0 are available at
For now I've left in place ( at https://wolfy.fedorapeople.org/nut ) the
old versions of nut I built 4-5 years ago but, if memory serves, those
were built for EL6 which has an year since it is no longer supported.
Therefore I recommend against using them and I will probably remove them
after New Year's day.
