No problem ... :

UPS:	Liebert PowerSure PSA 500
NUT:	Version 2.0.2
Kernel:	2.6.11.5, with CONFIG_USB_HID, CONFIG_USB_HIDINPUT, and
	CONFIG_USB_HIDDEV compiled in (statically)

================================================================

Driver:	liebert
Conn.:	Original RS232 cable

Starts OK, but fails to detect any events I tried (pulling mains, and 
pulling the serial cable). :-}

# upsdrvctl start

================================================================

Driver:	newhidups
Conn.:	Original USB cable

Driver fails to recognize UPS, in spite of the changes in /etc/hotplug. 
(Might be the result of my prior kernel fiddling, though ...)

Driver:	hidups
Conn.:	Original USB cable

Driver recognizes UPS and its state, but crashes and has to be restarted 
after every (so far) event.

(Unfortunately, the Liebert docs don't say what data *should* be 
available from *that* UPS model via HID; all I can say, with no Wintel 
box to run a test on, is that their MultiLink software's prepared for a 
*lot* more variables.)
