As I have already told it, I've done this, but it does not work. Chown/modding the /proc/bus/usb to nut:nut (the user:group which the daemon runs with) recursively (that means, every dir and every sub-dir and file of it, and ever subdir of every subdir, so on...) seems not to be enough, since newhidups is unable to find the device, as I have pasted it previously. > > If you do not have hotplugging or udev, then you cannot automate step > (2). > > -- Peter > > Czuczy Gergely wrote: > > > > Hello > > > > I'm having a bit of a trouble to set up a Back-UPS on > > a production box. > > We're using the newhidups driver for this module here, in > > the office, and I'd like to monitor the one, out in our > > server farm. > > > > The situation is the following: > > # /lib/nut/newhidups -u root -DD -a ups1 2> ups1.out > > Network UPS Tools: 0.28 USB communication driver 0.28 - core 0.30 > > (2.0.5) > > > > this one worked flawlessly, while as a user, it cannot access > > the UPS: > > > > # /lib/nut/newhidups -u nut -DD -a ups1 > > Network UPS Tools: 0.28 USB communication driver 0.28 - core 0.30 > > (2.0.5) > > > > debug level is '2' > > No appropriate HID device found > > No matching HID UPS found > > > > I've chowned to nut:nut /dev/usb/* and /proc/bus/usb recursively, > > but it didn't help. > > > > I'd like to ask for help, what do i need to adjust on the system > > to make it work. > > > > Some circumstances: > > This is a production box.
