I'm posting this since there's very little information available that explains how to resolve the following error message that you might receive on your Samsung TV. For many months, I have been receiving an error message pop up on the bottom left corner of my screen. The error message would say "USB Device Not Found. USB1 (or USB2) Power Overload." This message popped up without me ever doing anything with either USB port. In fact, I've never even used the USB ports on my Samsung TV. The message would appear at random and stay on for a few seconds or minutes. It's more annoying than anything.
To resolve this issue, I went to Samsung's website and navigated to their support section for my particular Samsung TV model. From there, you can download the latest firmware update for your TV and copy it to a USB flash drive. Once the firmware update is on your flash drive, you'll need to extract the files since they're zipped. At that point, you'll plug the flash drive into your TV's USB port. Go to your TV's menu and navigate to the section where you can update your firmware. On my specific Samsung, I went to my TV's Menu >> Support >> Software Upgrade >> By USB. This will start the update process and your TV will reboot once complete.
So far, my TV has operated great after the firmware update. I've not received the USB Device Not Found, USB1 or USB2 Power Overload error. Hopefully this will resolve the issue for me permanently. I'll update this post if the error message reappears.
