Hello, I bought a brand new Arduino nano for a project which required lightweight material. As soon as I received it, I opened Arduino IDE, grabbed a cable, and tried to connect my board to the Arduino IDE. But it didn't recognize my board. I had already coded a lot on other boards like the UNO r3 and the mega 2560 on the same computer and I had no problem with them so I know the problem doesn't come from the computer. I tried changing the USB port, but nothing happened. The power LED turns on and when I put an LED directly to the 3.3v and GND it lights up too but the Arduino IDE doesn't detect any upload ports. I tried to change computer, tried it on my laptop and it still didn't work so I am now sure that the problem doesn't come from the computer. I opened windows device manager and my board was displayed there as COM8 perfectly but still not on the Arduino IDE. I searched the internet and found an old discussion on this forum about the same subject, the guy said that his board was detected well by the online editor so I opened the online editor (which I usually never use) and tried to upload my code to the board from there... Of course, it still didn't work. So I opened this new discussion hoping someone will help so that I can go on with my project... 
Is it a "real" NANO or a clone? If it is a clone what is the USB-Serial chip? Do you have a driver for that chip installed?
If you have Python installed on your Windows unit, the serial port script is installed by default.
python -m serial.tools.list_ports
Otherwise, Microsoft has a downloadable utility called USBview:
Universal Serial Bus Viewer in Windows - Windows drivers | Microsoft Learn
Well, it looks like a real nano since Arduino's logo is written everywhere on the package and I bought it on www.store.arduino.cc...
Well that eliminated one possible problem. Did you try a different cable?
Hi @methething
Just to be sure, are you saying that COM8 is not shown in the Tools > Port menu in Arduino IDE?
Which version of Arduino IDE are you using (e.g., "2.0.1")? The version is shown on the window title bar and also in the Help > About dialog.
I ask for this information because I want to give you the appropriate instructions for the IDE version you are using.
I think it is written "Arduino IDE 2.0.3" on the window
I asked two questions. You answered only one of them. Please answer the other one:
well, actually, there is not any Tools>port menu in the app.
Here is a screenshot of where I think I should link my board and and you can see it doesn't find any upload ports even though my Arduino nano board is currently connected.
OK, that happens when no ports at all are detected (the behavior will be changed to always showing a Tools > Port menu item even when the menu is open in the next release of Arduino IDE).
I'm going to ask you to post some additional information that might help us to identify the problem.
Please do this:
- Start Windows "File Explorer".
- Open the Arduino IDE installation folder.
(usuallyC:\Program Files\Arduino IDEorC:\Users\<user name>\AppData\Local\Programs\Arduino IDE). - In the folder listing of the Arduino IDE installation folder, hold the Shift key while clicking the right hand button on the mouse.
- From the context menu, click "Open PowerShell window here".
Windows PowerShell will now open with the current directory set to the Arduino IDE installation folder. - Type the following command:
& ".\Arduino IDE" - Press the Enter key.
Debug output should now be printed to the PowerShell window as the Arduino IDE starts. - Wait for the Arduino IDE to finish starting.
- Switch back to the PowerShell window.
- Right click on the title bar of the PowerShell window.
This will open a context menu. - Select Edit > Select All from the context menu.
This will select all the text in the PowerShell window. - Press Ctrl+C.
This will copy the contents of the PowerShell window to the clipboard. - Open a forum reply here by clicking the Reply button.
- Click the
</>icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
- Press Ctrl+V.
This will paste the output into the code block. - Move the cursor outside of the code block markup before you add any additional text to your reply.
- Click the Reply button to post the output.
Please let me know if you have any questions or problems while following those instructions.
I followed each step succesfully, I just think there is kind of a lot of text in the windows powershell...
Anyways, here is what was prompted in the windows powershell:
PS C:\Users\flori\AppData\Local\Programs\Arduino IDE> & ".\Arduino IDE"

Haha, yeah it is a bit overwhelming! I get a lot of practice in searching through everyone's log output trying to find something possibly relevant to the problem they are having.
Unfortunately in this case I don't see any "smoking gun" in the logs.
You can see here that it did discover a serial port on COM9:
When you start Arduino IDE, is there still no port shown? I would expect the IDE to list a COM9 after showing this sort of message.
I'm also wondering about the discrepancy between the COM8 you saw in Windows Device Manager and the COM9 Arduino IDE is seeing. Does Device Manager still show the port as being on COM8? Ports do sometimes get assigned new numbers, so it is possible it changed from COM8 to COM9 since the time you checked last, in which case the discrepancy is not of interest, but usually they do stay the same so I think it is worth checking on.
Well, I have no idea what you did, but when I re-opened the Arduino IDE, it detected a certain "COM9"...
So I checked in the device manager and my Arduino nano had transformed into COM9.
I tried uploading a basic code on this COM9 (just a few lines that wrote "HIGH" on the pin D2) for debugging purposes... And it worked!!! 
I still have no idea what happened nor how you fixed it...
Anyways, thanks a lot for your help ! I can finally get on with my project !
If that is not too much to ask, can someone please tell me what was actually going wrong so that I know it the future?
You are welcome. I'm glad it is working now.
Unfortunately I have no idea. The instructions I gave you were only intended to gather information. They would not be expected to fix the problem. I know it is not so satisfying, but I think we will have to just be happy it is working now without knowing the reason. If the problem comes back, please let us know and we can do more investigation. There isn't much we could do to troubleshoot the problem when the system is in a working state.
Regards,
