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.

If I unplug the USB cable and plug it back in, usbhid-ups stops working
until I start and stop pwrstatd.
