Windows 7: USBs disconnect/reconnect during thunderstorms

First, unexplained because you did not do what must exist before any useful answer is possible. Again, "USB stutter is due to noise. Nobody can say anything useful until all connections are discussed. For example, is each USB device powered from its USB cable or via some separate power source. Remember, the noise (not surge) that might cause stutter must have an incoming path to that USB device. And a completely different and separate outgoing path. ... Solutions start by first defining a problem - every possible incoming and outgoing current path."

Obtaining schematics or proper tools is unnecessary. This is not a very complex subject. But every answer can only be speculation if a required above description is not provided.

Useful replies means ignoring some recommendations. A simple rule applies. If recommendations are not tempered by numbers, then ignore that source.

Second, a UPS or protector adjacent to electronics does not solve interruptions. Some reason why are repeated:

"noise current creates single digit volts. View numbers on that protector. It does absolutely nothing until [your] AC voltage well exceeds ... 500 volts."

"That stutter would be a canary in the coal mine. It is saying a transient must be averted where it enters a building."

"A "$1 per protected appliance" whole house solution is effective because (a) it makes a low impedance (ie less than 10 foot) connection to (b) single point earth ground. "

"First is to define incoming and outgoing paths via each USB device. Then others can define a problem BEFORE recommending a solution. Second is to have effective transient protection for all appliances - a 'whole house' solution."

To rephrase. UPS or protectors adjacent to electronics (and therefore without a 3 meter connection to earth) do nothing useful for this anomaly.

Every connection must be described. Every connected USB device listed. Every USB power source described. Is computer connected to an ethernet port? It must be listed. Is a mouse hardwired to the computer? List it. If every connection between everything is not listed, then no informed assistance is possible.

You have a UPS? Then every incoming and outgoing to that UPS even must be listed. If the connection is a two prong or three prong, well, that is two wires or three. Each wire must be known.

Connect an incandescent bulb to a same receptacle. If power (voltage) is changing, then bulb will obviously change intensity. That bulb (and behavior or any others) is a sophisticated diagnostic tool. Bulb can dim to well less than 50% intensity before AC power causes a computer problem.

Ignore replies that suggest unplugging is a solution. Unplugging is how to collect facts (a diagnostic). Unplugging is never a solution even to protecting hardware from direct lightning strikes.

Again, "If a surge is permitted anywhere inside, then well proven 'whole house' protection (with the always required low impedance connection to earth ground) is missing. Routine should be thunderstorms without any indication that a nearby strike existed (other than noise). Interruptions to USB devices or "irreversible damage" indicates a human mistake exists."

Long before interruptions can be solved, first the reason and source of that interruption must be defined.

Warning - Google "westom surge protection whole house" and you will see years of his same old blather on dozens of sites where it seems his apparent his goal is to sell whole house protection.

This is not me on some personal vendetta. He is constantly spewing nonsense and outdated facts, calling those who call him out as liars, fools, uninformed and more.

He is stuck in the past believing all homes are wired like DCOs (telephone company dial central offices) and all electronics behave like big household appliances. He regularly claims that all appliances already have and always have had "robust protection" and he insists that "Protection is only as effective as its single point earth ground. As demonstrated by so many facts with numbers. And by over 100 years of well proven science and experience." always refusing to explain how airplanes are stuck 1000s of times each day without harm, or what happens when a high wattage appliance (like a cheap 1500W hair dryer) in the house fails.

It is clear he "trolls" the Internet to look for any references to UPS and surge protection so he can start his rants.

He then goes on to claim all electronics MUST have surge protection, that UPS makers don't claim to protect the connected devices. Yeah right. Then he proceeds to promote "whole house" surge protection totally ignoring the fact that many destructive surges and spikes don't have to originate from the grid, but can and do come from faulty devices within the home.

Note at WindowsBBS where westom claims Ethernet has robust protection up to 2000V then see Bill's post#9.

Note Toms Hardware where zherot says,

You again?, i swear every surge protector post in this forums you always come to say the same damn thing yet you dont offer any kind of solution its like you only enter to tell people they are idiots for wanting to protect theis systems.
And more examples:
I go through a router every 3 years and I had someone tell me don't use surge protec | MajorGeeks.Com Support Forums - note he says all routers have protection up to 2000V too.

I can go on and on, but the point is made.

Thank you for your post Itaregid.

Very good information. I does explain a lot about our westom and the possible angle he is coming from.
