I got stuck slightly having /usr on lvm as this was unmounted before bcmxcp_usb was called to kill power. $ ldd /lib/nut/bcmxcp_usb libusb-0.1.so.4 => /usr/lib/libusb-0.1.so.4 (0x00002addf3530000) libc.so.6 => /lib/libc.so.6 (0x00002addf3638000) /lib64/ld-linux-x86-64.so.2 (0x00002addf3413000) (not a big concern for me - I'm going to try to move to a hibernate on powerfail.)
This fix to libusb should have been committed already?
true - libusb-0.1.12-r1 I was using libusb-0.1.12 thanks
