Power surge on USB port (Windows 10).

[thecomputerguy]

I got a Dental client who uses an All-in-One PC attached to an arm in her operatory. She recently started getting power surges on USB ports with various USB devices like the intra-oral camera and USB x-ray device. I suspect the USB ports were not treated ... well, nicely over the life of this computer. There has been lots of various USB devices plugged and unplugged into this PC.

Has anyone ever fixed this as a software issue or is it almost always a damaged/shorted USB port?

Edit: Windows 10 Pro, I just updated chipset and BIOS to see if that helps.

Have you inspected the USB ports to see if there is damage?

Boot it in a live environment (Windows, Linux, whatever you prefer) and test the USB ports from there. If they work properly it could be a software/driver issue. If they don't then it's time to sh*tcan the AIO. This is why I don't use AIO's, ESPECIALLY in business environments.

I have yet to see this issue crop up and not had it result in a new machine. You have a physically damaged USB port in there somewhere, if you stop using it you can work around the problem but the bottom line... the unit is broken.

In the future maybe get them a usb hub? That way the hub stays in and things plug in and out of the hub. That way if a port gets damaged just replace the hub and move on

USB power surge? Never heard of such. How does a 500 mA device power surge? (USB 3 is 900 mA...)

I think perhaps you used the wrong word? Do you mean blinking power perhaps?

Then it should be a powered USB hub.

I've had issues with the motherboard not being able to power all the ports. I use a USB hub for everything except keyboard and mouse. That way you are certain that the accessories receives the correct power output. And I'd rather have the USB hub get borked than the computer itself.

Sometimes see computers with broken USB ports though.

Like overburnz said, get a flashlight and and a magnifying lens and examine every USB port closely. Also check the USB cable connectors. You will find some mangled/bent pins.
