[Nut-upsuser] Is newhidups driver still in memory just before o/s halt ?

[Marc Rechté]

Hi,

I have set-up the ups shutdown feature provided by Red Hat 
/etc/rc.d/init.d/halt script, which will issue a "upsdrvctl shutdown" 
command just before powering off the system.

It appears that this command fails as if the driver is not available.

I wonder whether the usb driver / stack is still available at this very 
late stage ?

If not available then does it mean one cannot shutdown the ups ?

Thanks to all.
