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
Network UPS Tools - UPS driver controller 2.0.2
Network UPS Tools - Liebert MultiLink UPS driver 1.0 (2.0.2)
Warning: This is an experimental driver.
Some features may not function correctly.

===============================================================
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 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.)
