Setup that I was on mind is a little different, but I think your setup works
well.
In my setup the HUB is connected directly to the UPS, then the cables go to
raspberry and device.
In your setup the HUB is connected directly to the raspberry, then the
cables go to UPS and Device.
It?s Ok?
In both configurations I need the same things: Male B->female A adaptor, HUB
and 2 male A-> male A cables.
The male A- male A cables have any peculiarity? Can I buy it or make it
myself without problems?
Thanks a lot for advice.

to male, one to raspberry and another one to my device.
I'm not sure I understand your setup.
This should work, using standard USB cables:
<- upstream downstream ->
<- host device ->
A->B A->B
Raspberry Pi -> hub -> UPS
|
\---> device
The problem is that there is no equivalent of a "crossover cable" or
"null-model adapter" for USB. (I am ignoring USB OTG
<http://en.wikipedia.org/wiki/USB_On-The-Go> for the moment, since you
want
the RPi to talk to the UPS). There are many USB adapter cables out there
that will only work for supplying power, or only with point-to-point USB
OTG.

In my mind, the presence of an A-to-A cable indicates a problem in the design :-) Wait, are you just trying to use the UPS for 5VDC power over USB for the other device? The diagram I drew shows how to connect the UPS to the RPi for monitoring, through the hub. Other configurations are possible if you don't need to monitor the UPS.> It?s Ok? > > In both configurations I need the same things: Male B->female A adaptor, HUB and 2 male A-> male A cables. > The male A- male A cables have any peculiarity?

So, the hardware way seems too difficult. I see the raspberry documentation in order to understand if it?s possible ?replicate? an USB signal to GPIO. So, with a TTL-USB cable I send the signal to the NVR. I hope this is possible!
