the keyword "linux 2.6.14" directly tells us that it's something with udev.
- before 2.6.12, only hotplug was needed
- between 2.6.12 and 2.6.14, udev takes an interim with hotplug compat
- as of 2.6.14, only udev is involved.
The necessary scripts are present in the CVS Testing and Dev tree, and will
be included in 2.0.3. But it only applies to newhidups and libusb. For
hidups, which uses linux hiddev driver, you need to change something in the
devfs.rules to adapt the device's ownership or to include the "ups" group in
the "usb" group (not sure, validate with an "ls -l" on the hiddevX device
- Peter _is_ a NUT Developer. And not a least one ;-)
- I'm finishing some audit for these hotplug scripts to be documented in
- prefer to switch to newhidups as hidups will soon be dropped in favor of
