system : win 10 pro
 my system with PLM 2413U was running fine since win 10 
 upgrade for almost a year ago.
 for past few weeks its losing communication with PLM 
 an errors out only in PH. it could take few hours and 
 then you see the error some time PH can over come.
 
 if PH eliminates the controller and you re-initialize 
 PH  it will start working again. 
 
 what I have done:
 make sure no power saving.
 make sure updated drivers.
 swap the system with same hard-drive- same problem
 (so eliminate the USB could be bad)
 swap the PLM same problem.
 use different outlet of PLM
 use my backup copy of database which was know to be 
 working.
 
 any time PH has communication error device manager 
 still shows PLM connected.
 
 Not sure but window 10 had some updates in last few 
 weeks -  may be that cause this to fail.
 
 I still have to try few other things like I have 2413S 
 which is serial version - (I did not had the extra 
 serial available on this computer just got the extra 
 port so will try that.)
 
 need to find my old build of win 7 or XP to eliminate 
 windows 10 issue . ( I know win 10 has change the way 
 permission of App work thru registry edit)
 
 
 Not sure anyone had similar problem.

so after so many different try - seems like its a 
 noise issue. 
 
 I found that if PLM is plug into current outlet I get 
 communication error and eventually PLM will lock .
 if plug into little away (with short extension cord) 
 outlet few errors.
 long extension power cord from different room - no 
 error.
 
 I found that next bed room had a bed light with 
 transformer which we had for 4 years and no problem 
 since that time. I unplug that for a 24 hours and no 
 error for now.
 
 I know transformer can go bad and create noise even 
 the lights are working.
 
 My situation was hard to find since it would take many 
 hours before it start to fail and can start working by 
 re-initializing  PH.

Thanks for posting your follow up.
 
 Those sporadic, non-repeatable problems are really hard to track down, glad you found it!
 
 
 I am still battling a situation where I see the controller lose PH connectivity when I have lots of Insteon lights on/dimmed (like when we are having a house party).
 
 I am still looking for a good "Insteon stress test" to see if I can make this very non-frequent thing repeatable; and then hopefully "fixable".

Nick,
 
 Ive had occasional instances of this as well. Everything is working fine and then suddenly, I cant seem to control anything Insteon.  Im using an 
 original hub right now as my controller and earlier I was using the Insteon PLM stick so never saw the controller errors.
 
 Most of the time for me, it was a failed Insteon switch itself. The switch could still work, etc. but was just generating a ton of noise or bad 
 signals. I usually have to locate them by switching off breakers (to narrow it down). But once I find it, I replace the switch and all is good 
 again.
 
 Glad you were able to find the problem though. These types of errors are very frustrating.
 
 Dave.
