Hi,

I have included debugging logs-- see below, is this a nut or kernel/USB subsystem issue?

There are no kernel messages in dmesg/syslog that relate to this event. The same exact hardware was used on a different motherboard (DG965WH) without any problems.

Hello,

I use the following in my ups.conf:

# USB:
[apc]
driver = usbhid-ups
port = auto
desc = "APC 1500VA"
pollfreq = 5

On my new motherboard (an Intel DP55KG), every once and awhile I get this:

Broadcast Message from [email protected]
(somewhere) at 17:48 ...

Communications with UPS a...@localhost lost


Broadcast Message from [email protected]
(somewhere) at 17:48 ...

Communications with UPS a...@localhost established

On my previous motherboard (a DG965WH), the exact same configuration was
used
and I never had this issue.

Any hints?

Should I increase the pollfreq to say 30 seconds?

Would this 'workaround' the problem?

Is this a known bug on this chipset?

Anything unusual showing up in dmesg?



Robert/Nut User List--

Looks like the data goes stale, please let me know if any more logs/debugging is required, is this a kernel/usb problem or a nut issue? I recall a change in the USB subsystem a few kernel versions back caused a different issue (on a different UPS, but nevertheless it was kernel related).

The details+logs are here (previous e-mail did not go through, too large for the list):
