You are asking for free help, which implies a very simple deal: I ask
you questions that I think are useful, and you answer them. If you are
lucky, we find out what the problem is. I ask my questions for good
reasons; I did not need you to argue for three days over whether they
suit your taste. And yes, sometimes it is necessary to repeat an
experiment even if you have done it before.

Apparently a 2.4.32 kernel.

Excellent.

See, you can provide some useful information. It seems to me that the
problem is outside of NUT, but we might be able to find out more about
it.

(1) Could you please run the two commands again, but this time, with
the environment variable USB_DEBUG=3, i.e., like this (assuming you
are using bash):

USB_DEBUG=3 /lib/nut/newhidups -u nut -DD -a ups1
USB_DEBUG=3 /lib/nut/newhidups -u root -DD -a ups1

Please post the output. 

(2) is your machine running any access control system, such as
SELinux, which might restrict access to the USB system?

(3) I assume that you have run the command "/lib/nut/newhidups -u nut
-DD -a ups1" as the root user. Is this correct? 

(4) I would still like to see the output of "ls -lr /proc/bus/usb". 

Thanks, -- Peter
