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?
Please provide a link to the product.
Does it see unknown devices when you connect?
Try the steps below:
- Uninstall the 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.
- Install the board’s package core, https://www.arduino.cc/en/Guide/Cores
- 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.
- Make sure you select the board and the port it is connected to before uploading a sketch.
- 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.
