It may be a while before I can take the system down to experiment with
different kernel versions.
Most reports of the kernel timeout problem that I ran across in my
searches seemed to relate to a missing HID_QUIRK_NO_INIT_REPORTS quirk
for the device.
I did try replacing the USB cable, and bypassing the USB hub that I was
using by connecting the UPS directly to one of the USB ports on the
motherboard. This didn't seem to make any difference.
Just for grins, I downloaded Cyberpower's PowerPanel for Linux and it is
able to find the UPS.
# pwrstat -status
The UPS information shows as following:
Properties:
Model Name................... PP1100
Firmware Number.............. 1.610
Rating Voltage............... 120 V
Rating Power................. 700 Watt(1100 VA)
Current UPS status:
State........................ Normal
Power Supply by.............. Utility Power
Utility Voltage.............. 121 V
Output Voltage............... 121 V
Utility Frequency............ 60.0 Hz
Battery Capacity............. 100 %
Remaining Runtime............ 35 min.
Load......................... 231 Watt(33 %)
Line Interaction............. None
Test Result.................. Unknown
Last Power Event............. None
What is even more interesting is that after I kill pwrstatd, usbhid-ups
is able to detect the UPS and nut seems to function correctly.
