Arduino uno not recognized by my pc

Development Tools Uploading

Hi everyone!

I just bought my first arduino for a school project. It's an Arduino Uno.

The problem is that my win11 pc can't see the device. It is not in device manager (not other devices or anywhere else). I got a program called USBVIEW and when I plug in the arduino, it's not showing up there.

First I installed IDE, and i found the drivers folder and installed the drivers, but still not working. I'm using the cable that I got with the arduino. I also tried it on my laptop also with win11 and there is the same problem.

It has power when I plug it in. ON lights up, and the LED next to a "L" is blinking slowly.

Is it a genuine UNO or a clone?
If a clone does it have the CH340 IC.

COMMON ISSUES

  • Ensure you have FULLY inserted the USB cables.
  • Check you have a COMMON GROUND where required. ( Thanks Perry)
  • Where possible use USB 2.0 ports or a USB 2.0 POWERED HUB to rule out USB 3.0 issues.
  • Try other computers where possible.
  • Try other USB leads where possible.
  • You may not have the correct driver installed. CH340/341 or CP2102 or FT232 VCP Drivers - FTDI
  • There may be a problem with the board check or remove your wiring first.
  • Remove any items connected to pins 0 and 1.

It is a genuine UNO.
The USB cable is fully in.
I'm using USB 2.0 port. But I tried USB 3.0 port too.

How do i know which is the correct driver for my device?

I think it's not the driver because it does not show up as an USB device anywhere. No sound from my pc like when I plug in any other USB device.

It will not matter if you install additional drivers from the links I gave you.
Good pictures of your board may also help us.
What is your OS as that can also come into play ?

I can install a virtual Linux if needed.

I have some doubts that it's genuine. Compare your image with the image on Arduino Uno Rev3 — Arduino Official Store. Colour is wrong and the print of the board identification / Arduino logo on the top is missing

That is the Tx LED and it is driven by the 16U2. The fact that your board is not recognised as well makes me think that the 16U2 is not correctly programmed by the manufacturer or is faulty.

If you don't want to ship it back to the seller you can try to program the 16U2 using the Atmel flip program and the 6-pin header close to it. You can find instructions on the web.

No, it's the LED_BUILTIN that's drivin by the 328P
P.S. It's definitely NOT a genuine UNO.

My mistake, misread it as " next to the L-LED".

Have you tried a different USB cable as previously suggested by @Ballscrewbob? Perhaps you have a power/charge only cable, which only has/uses the 5V and GND wires.

Unfortunately I don't have another cable of this type, so I can't try it.
But the cable seems fine.

I'm 99.999% sure that there is no such thing as a Type-B charging cable.

That is one of the Chinese USB cables.
They often fail..

You can pick them up quite easily and cheap in thrift stores from printers and such and they are usually better than the Chinese ones.
I try get the ones with a ferrite core built in.
