Arduino Uno does not recognized on win 10 pro as I only have usb 3 ports on my pc

So what have you plugged the Uno into ?

Try the following and see if it resolves your issue:

  1. Try a new USB cable making sure it is a DATA USB one not a charging cable.

  2. Make sure the board is directly connected to the USB port without a USB hub in between.

  3. Make sure AVR core is up to date on Arduino IDE > Tools > Boards > Board Manager: search for Arduino UNO and update/install the AVR core, that is, the latest version.

  4. Open device manager connect board to PC and see if anything new shows up in either Port (COM & LPT) or Other Devices

  5. Connect the board to a different computer and check if it has the same behaviour.

I do not have another cable as I only got 1 from the seller that sold me this online.
Also it (not) "recognized" as USB2.0-Ser with warning as this is not working or recognized, in device manager in my pc

Does the L-led blink rapidly when you press the reset button?

yes and there is a sound of windows that there is something that just git connected to the pc

Sounds like you need a driver. For that you need to identify the chip closest to the USB port. Right click the USB2.0-Ser in Windows device manger and select properties; it might already tell you what you have (e.g. CP2102, CH340, FT232, ...). If not select the details tab and select Hardware Ids and note down the VID and PID and look them up on the web. For the CH340, it would look like below

Next you will have to find the drivers on the manufacturers website. For the CH340, download the zip from CH341SER.ZIP - NanjingQinhengMicroelectronics, extract it and run the exe to install the driver.
