[Nut-upsdev] Newhidups gets unbound after a while

[Patrick Agrain]

Hi everybody,

If we let the feature running, it appears that the driver gets unbound 
after a while ( variable from quarter of hour to 6 hours ) and cannot 
reconnect.
This behavior appear with both MGE Ellipse ASR and non-ASR models with 
connection to an UHCI and OHCI controllers.
The USB core is from 2.4.28 kernel.
We use nut-2.0.3.

Start, powerfail and recovery detections, UPS shutdown work very well. Only 
continous scanning seems to fail.

Following are the logs:
[root at xa000000 root]# newhidups -a ups_on_usb -DD

Looking about the reason of the disconnection, I tried gdb but it failed ( 
received : warning: Couldn't get registers ). Any ideas about what I could 
also try ?
For the non-reconnection problem, I suspect a pointer problem, but with no 
more precision. I had less time to dig further.

Let me know if you need other logs.

Any help will be appreciated.
