USB port malfunctioning, always says "USB Device not recognized"

Anonymous

I have a samsung laptop, model number NP350E7C-A01US. Every time I insert anything into one of my four USB ports, I get the error: "USB Device not recognized".

You can see the laptop here: https://www.samsung.com/us/support/owners/product/NP350E7C-A01US

Have you had a look in the Device Manager for any errors with the USB devices?

Use Device Manager and uninstall the USB root hubs and devices that show on your machine now. Reboot and let Windows rediscover them and see if that solves your problem.

See one way that you can access the Device Manager via Control Panel\All Control Panel Items\Administrative Tools\Computer Management\Device Manager. There are several ways to get there.

Try hardware troubleshooter WinKey + W >Troubleshooter > Heardware and sound.

Also try opening Device Manager and seeing if when you plug it in you get a notification of it not working or trying to install

You can look in View Event Logs to see if it picks up an error. When you open it using WinKey + W > View Event Logs > connect the device and refresh the Event logs to see the summary a new event should popup

See if these allow you to get it working

Start up using Clean Boot

Startup using Safemode

What is the USB device you are plugging in?
