[Bendtsen, Jon]

Hi

Yesterday I had 2 different APC UPS using USB get in power off recoverable state.

The machine is a guruplug server plus, running debian lenny on armtel. Linux dkplugbab9 2.6.32-00007-g56678ec #1 PREEMPT Mon Feb 8 03:49:55 PST 2010 armv5tel GNU/Linux

I have hand installed Network UPS Tools upsstats 2.4.3 from source.

ups.conf:
[apc1500]
  driver = usbhid-ups
  port = auto
  serial=AS0535132782
  # powers switches and routers

[Smart-UPS_3000]
  driver = usbhid-ups
  port = auto
  serial=JS1030003421

[R3000XR]
  port = /dev/ttyUSB0
  driver = bcmxcp


The R3000XR did work, but neither apc1500 nor Smart-UPS_3000. I tried restarting nut, I tried in other linux servers (just plugging in and seeing dmesg). Nothing helped. So I scheduled downtime and powered off the UPses. That did help, and since that nut has been able to monitor the UPSes.
