for the error even though permissions are OK (or the driver is run as root). Nut uses libusb-0.1 API, assuming return cods of < 0. FreeBSD provides a libusb-0.1 wrapper howerver it uses libusb-1.0 error codes (which are negative). This set of patches "teaches" nut libusb-1.0 error codes as produced by FreeBSD. Network UPS Tools (networkupstools.org) has a project to use libusb-1.0. This commit is a stopgap fix until our upline implments lubusb-1.0 support in nut. PR: 223117 Submitted by: lev
