You would need to record the exact time when it shuts down, I think.

Hmm, then the driver should be doing the same thing.

What does the debug output look like when you run ./nutdrv_atcl_usb -a ups -DDD
-u root -k ?

Where do you mean? It looks like the host resets the USB port about 7 seconds
after sending the Interrupt Out (packet #221 in the latest capture). If the
Windows application doesn't reconnect, that would explain the lack of
Interrupt In packets after it is finished enumerating.

If it works for you, then that works for me.

Thanks for testing,

Then, 60 seconds afted the command exits, the UPS turns off. This only
happens on batteries, on AC the output is the same but the ups does not
turn off.

Yes, the resets are sent when windows powers down, but the ups remains
on a minute after that and during that minute, no traffic is sent on the
bus, probably as you said, because the port is reset.

It does indeed :D
Thank you for adding support for this UPS :)

[Nut-upsuser] Generic UPS driver

One small comment:
When the driver has no permission to access the device, it exits with a
segmentation fault, it would be nice to have a more informative error.
I'm not really sure if the issue is speciffic to this driver or is it
general.

I attached the output of an strace with the driver crashing.


Best regards.

[Nut-upsuser] Generic UPS driver

Good point. I forgot that the permissions errors would happen after the numeric
device IDs were matched.

I just pushed 3c13603. Tested by telling the driver to match a random USB device
instead of 0001:0000, and sure enough, when the driver didn't have write
access, the unpatched code crashed. Not sure I want to try and send UPS polling
commands to either a working UPS, or the mouse or keyboard, so I'll leave
the rest of the testing to you :-)

scripts/udev/nut-usbups.rules should have an entry for 0001:0000 (although the
comments mention a different driver). You may have to refresh udev somehow to
get it to fix the permissions on the UPS, although we have had reports that the
rules file silently fails on non-Debian-derived systems.
