[Nut-upsuser] APC Smart-UPS 1500; system shutdown is not initiated.

[Christian]

Dear list,

I have an APC Smart-UPS 1500 hooked up via the USB port. Recently, when
we had a power outage, the only entry in the logs was:

Dec  3 14:43:43 afs1 upsmon[3035]: UPS apc at localhost on battery

and then the machine seems to have run until the battery was empty. It
only notices the "battery low" after I turn the system back on:

Dec  3 16:01:39 afs1 usbhid-ups[21973]: Startup successful
Dec  3 16:01:39 afs1 upsd[21975]: listening on 192.168.103.221 port 3493

[apc]
Dec  3 16:01:39 afs1 upsmon[22056]: UPS apc at localhost battery is low

Any ideas?

I include my config below... Thanks,

Christian

nut is debian wheezy's 2.6.4-2.3.

/etc/nut/ups.conf:
[apc]
        driver = usbhid-ups
        port = auto
        desc = "APC SmartUPS 1500"

Occasionally, i get these in daemon.log:
Dec  4 03:11:54 afs1 usbhid-ups[21973]: libusb_get_interrupt: could not
claim interface 0: Device or resource busy
Dec  6 11:50:55 afs1 usbhid-ups[21973]: libusb_get_interrupt: error
