Now that libusb-1.0 is becoming more mainstream, we should probably
update our documentation.
As you found out, there are two incompatible APIs: 0.1 and 1.0.
From what I can tell, libusb-1.0 does not offer much beyond what we
already get from libusb-0.1.12. So, for the foreseeable future, we
will probably stick to the libusb-0.1 API.
The simple solution for now is to use 0.1.12. I think I remember
hearing that both can be installed at once, but NUT is currently
looking for 0.1.x.
Hopefully I will have some time later today to take a more in-depth
look at your original problem. On the other hand, if the driver is
working in debug mode, our efforts might be better spent on creating a
solid example launchd script for running the driver.
