Subject: USB/UPS connectivity issue on Intel DP55KG Motherboard

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 nut@....com
         (somewhere) at 17:48 ...

Communications with UPS apc@...alhost lost


Broadcast Message from nut@....com
         (somewhere) at 17:48 ...

Communications with UPS apc@...alhost 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?

Justin.
