Issue with Detecting Port on Arduino IDE (Port - Greyed Out)

Development Tools IDE 1.x
1

Hello,

I've downloaded Arduino IDE on my Windows 10 computer and am trying to upload my written code onto my Arduino Uno microcontroller. I have already plugged in my USB cable into my computer. However, when I go under Tools to select the port, the Port option is greyed out.

I don't know what seems to be the issue. I tried different computers, but both had the same problem. I remember being able to successfully do this a few years ago on one of my computers. I don't know why its not working now. I looked through some troubleshooting options under Device Manager, but nothing has worked so far.

While I'm not sure what the problem is, there is a exclamation point on USB Serial 2.0 and on COM Port 3 under Ports (COM & LPT). Also when I plug in the USB cable, it states that driver is unavailable. What does the mean? I downloaded everything I needed when I installed Arduino IDE. Why is it saying that a driver cannot be found?

What is written on the chip next to the USB port?

On the microcontroller chip? It just says Uno.

No, not on the board. It's the little black device closest to the usb connector.

On original Arduinos, it's square with legs at all sides and should read 16U2. If it's a rectangular chip with legs at two sides you have clone; decipher the writing (very often it will be a CH340) and download the driver. For the CH340/CH341, the driver can be downloaded from the Chinese manufacturer's website.
