Just a small update; I figured out the udev script so now the processes don't run as root and all still works :-). Thanks for all your help. The only remaining issue is the intermittant failures when the driver is loading..

Hi Arjen,<br>Many thanks for your on-going support on this. It seems to be working 'mostly' fine now. Just a few points:<div class="Ih2E3d"><br><br>>> The better option would be to modify the udev/hotplug script and not run
<br>everything as root.
<br><br></div>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?<br><br>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?
<br><br>Thanks,<br><br>Joe<br>P.S. If you need my exact config maybe you want to document this a working UPS on the NUT page :-).<div><div></div><div class="Wj3C7c"><br><br><br><br><div class="gmail_quote">On Jan 3, 2008 8:17 AM, Arjen de Korte <
