When I check the configure log, it says "libusb-0.1.12"  I'm not sure why it says that, as in where it gets that value, as that version doesn't correspond to anything I installed.  I see looking at the last version of libusb-0.1 that was available, it was libusb-0.1.12, so it must be getting that version number from the libusb-compat layer, as I did not install the old libusb-0.1.12 on this last test.

This is the crux of the libusb-1.0 problem for NUT: a lot of time has been spent making things work with libusb-0.1 and the kernel, and now, instead of three moving pieces, we have four (counting NUT itself, with the addition of libusb-compat in the middle).

As I am not familiar with openSUSE's ldconfig, is there an /etc/ld.so.conf or /etc/ld.so.conf.d/* entry pointing to /usr/local/lib64? I am not sure if libusb-0.1 tries to rerun ldconfig after installing, but if after uninstalling libusb-compat, there are problems linking to the real libusb-0.1, then it can't hurt to re-run ldconfig (as root).
