[Nut-upsuser] Need help with Unitek Alpha 1200sx.

[Joseph Borg]

Hi Arjen,
Many thanks for your on-going support on this. It seems to be working
'mostly' fine now. Just a few points:

>> The better option would be to modify the udev/hotplug script and not run
everything as root.

Any pointers on how to do the above? NUT installed from RPM for me so
presumably I can get these scripts by downloading the .tar.gz. What needs
modification in them?

Most of the time, the driver seems to load fine on restart/boot-up. At time
however, it does not seem to load and will not load no matter how many times
I try after. In order to overcome this I have to switch off the PC, switch
off the UPS and then start afresh (switch-on). It therefore seems as though
the USB/Serial connection is 'stuck' at times and needs some sort of reset.
Is this a known issue and/or is there any way I can overcome this?

Thanks,

Joe
P.S. If you need my exact config maybe you want to document this a working
UPS on the NUT page :-).
