Looks like Ubuntu fixed 2.4.3 here: https://bugs.launchpad.net/ubuntu/+source/nut/+bug/572262 That was committed to NUT here: http://trac.networkupstools.org/projects/nut/changeset/2407 This breaks reading larger reports, so it was reverted: http://trac.networkupstools.org/projects/nut/changeset/2719 This patch (committed after 2.6.0 was released) claims to restore 2.4.1 behavior: http://trac.networkupstools.org/projects/nut/changeset/2893 Arjen: do we actually have any cases of reports larger than 8 bytes? If so, should we mark this as a quirk for CyberPower devices? Also, it seems like we need to distinguish between returning 0 and <0 from the libusb call. Currently, we are reading errno when a zero-length packet is being read. -- - Charles Lepple _______________________________________________ Nut-upsuser mailing list Nutfirstname.lastname@example.org http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
