I have an Arduino Uno R3 that I got in a starter set today and I'm unable to get my computer to detect it through my device manager and my ports on the arduino. I have checked multiple articles and can't find a solution, help would be extremely appreciated.

Are you using a data cable, not just a charger cable? Is anything connected to the Uno? Like modules or other loads? What are the LEDs on the Uno doing?

Does it see unknown devices when you connect?

Try the steps below:

1. Uninstall the IDE ([https://support.arduino.cc/hc/en-us/articles/360021325733-How-to-do-a-complete-uninstall-of-the-Arduino-IDE](https://support.arduino.cc/hc/en-us/articles/360021325733-How-to-do-a-complete-uninstall-of-the-Arduino-IDE)) and then install the latest version.
2. Install the board’s package core, [https://www.arduino.cc/en/Guide/Cores](https://www.arduino.cc/en/Guide/Cores)
3. Use a good quality data USB cable to connect the board to the computer without anything connected or wired to the board. Do not use USB 3.0 port or USB hub.
4. Make sure you select the board and the port it is connected to before uploading a sketch.
5. If 1-4 above fails to solve it, double tap the reset button fast and check the status of the L LED onboard. If the onboard LED fade in and out slowly (pulsating), upload an example sketch from the IDE the board.

Does your windows os make a sound or file manager show a device when your arduino is inserted?

I know that you're (mostly?) a Linux user but it _device manager_ 😃

Yes, Hardware Device Manager is right...

...but, when I use Windows File manager, I can see devices on the (WinE-F9) left side panel that are available for use as a general user, whereas, hardware manager shows all devices present, some I can not obtain access without being very knowledgeable.
