Китайская(Вроде бы. На всякий случай прикреплю фото
).Драйвер ставил не помогло.
- не установлены ∕ застарели драйвера (скачиваем ∕ обновляем их);
- неисправен USB-кабель или порт;
- заводской брак ∕ не прошит микроконтроллер;
- возможна блокировка ОС;
- повреждена ∕ неисправна сама плата Ардуино.
Ошибка № 3 – практика показывает, что очень часто дело именно в микроконтроллере ATmega16U2, который отвечает за коммуникацию по USB. Его следует обязательно прошить и делается это вручную. Порядок наших действий следующий: отключаем плату от ПК, замыкаем между собой контакты на несколько секунд (см. на скриншоте):
Снова подключаем Ардуино к девайсу, размыкаем контакты. Теперь комп видит «неизвестное устройство», для которого необходимо установить драйвера:
http://www.atmel.com/Images/JRE%20-%20Flip%20Installer%20-%203.4.7.112.exe
Запускаем Atmel Flip:
В подменю «Device Selection» выбираем ATmega16U2. В меню «File» кликаем «Load HEX File», нам нужна прошивка Arduino-usbserial-atmega16u2-Uno-Rev3.hex
В меню «Settings → Communications» следует выбрать связь по USB. Теперь кликаем Run и дожидаемся окончания процесса прошивки. Заходим в Диспетчер, там должна появится такая информация:
Если ничего из описанного выше не сработало, и все манипуляции были напрасны, скорее всего ваша плата находится в нерабочем состоянии, а потому подлежит замене.
Arduino COM port not found
For the past week I have been programming an Arduino Uno with a computer running Windows 7. When I first started, I found the device on COM6 and was able to upload code no problem. Recently it suddenly stopped receiving code under the error:
Serial port ‘COM6’ not found. Did you select the right one from the Tools > Serial Port menu?
The Serial port menu though is grayed out. Research has told me to open up Device Manager and update drivers but there is no other devices tab in my Device Manager. The Arduino is run off the power of the USB cable and runs the code I uploaded a few days ago just fine. What can I do to be able to upload code to the Arduino?
Update:
I installed the Arduino software on another computer and it does not recognize the Arduino either. One of the comments indicates that this could be a problem with the FTDI chip. How can I test if this is the case, and if it is, can I fix it?
Fix Arduino Port not Showing Up or not Detected [IDE, UNO]
Here's how to easily detect Arduino ports if they fail to show up in Windows 10 or 11
- If an Arduino port is not showing up, your USB connection might be faulty or the ports may be disabled entirely.
- We will show you how to enable a port in Arduino and look it up in the Device Manager.
- Should Arduino fail to detect any ports, you might need to update or reinstall the drivers.
- Download DriverFix (verified download file).
- Click Start Scan to find all problematic drivers.
- Click Update Drivers to get new versions and avoid system malfunctionings.

Development boards like SparkFun RedBoard for Arduino require special drivers or code that lets your PC interact with them. If the Arduino port is not showing up on your PC, you’re in the right place.
We will show you how to enable a port in Arduino, and properly update, or install Arduino port drivers on your Windows, or Mac OS.
Let’s see why the port is disabled or now showing in Arduino, to begin with.
Why is my Arduino port not found?
- Faulty USB cable or connection
- Port drivers are deprecated or corrupted
- Drivers are not installed
Now, users have had a hard time with this for quite some time. Let’s quickly go through some of the most common issues:
- Arduino port not showing up Windows 10, Windows 11, or Mac
- Arduino port not detected, no ports discovered or not recognizing port
- Serial port not selected Arduino
- Arduino USB, OTA, NANO port not showing up
- Port not showing in Arduino IDE
- Arduino port not showing in Device Manager
- Arduino port greyed out
How do I enable Arduino ports?
1. Verify that ports are enabled both on the board and on the PC
- Open the software and go to Tools, then access the Board menu.
- Locate the Port menu and hover over the option to display all the ports (COM, respectively LPT).
- Verify if there is a board connected to the port you’re interested in (the name will be shown after the port).
- If not, make sure your board is connected to the computer and restart the software.
- Open the Device Manager and head over to the View tab.
- Select Show hidden devices from the drop-down menu.
- Locate the Ports section and expand it to identify COM, respectively LPT ports.
If you need further help on how to show hidden devices in Device Manager, we have some extra tips for you.
2. Update Arduino drivers
- Open the Start Menu, and type Device Manager on the search bar.
- Click the Device Manager icon to open a new window.
- Scroll down to Software Devices and click to expand.
- Double-click the unknown Arduino device for the Properties window to display.
- Select the Driver tab, and click Update Driver .
- Choose the Search automatically for drivers option.
- Windows will begin to update.
- Run a final check to be sure the driver was updated correctly.

Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken.
We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.
Click here to download and start repairing.
If your Arduino drivers are not up to date you will usually get Arduino ports not showing up. Update them accordingly.
However, if this method fails, you will have to reinstall the Arduino driver to fix the issue.

3. Install Arduino port drivers
The next solutions will show you the right ways to install the driver on Windows and macOS.
3.1. Install Arduino drivers on Windows
- Click the search bar and type Device Manager . Open it.
- Check the options under Ports COM & LPT. You will see an open port labeled Arduino UNO COMxx .
- Right-click on the Arduino UNO COmxx and select Update Driver.
- Continue by clicking the Browse my computer for driver software option.
- Navigate to the driver folder of the Arduino software, locate Arduino.inf driver file, and click on it.
- After selecting the file, click OK.
When an Arduino board is plugged into a Windows computer, a driver is installed automatically for it to be able to communicate properly with your PC.
The driver configures it as a virtual COM port in the Device Manager. Should you require further assistance on how to install Arduino software and drivers on Windows, we have some extra tips for you.
3.2. Install Arduino port drivers on Mac
- On your Mac OS, go to the FTDIUSBSerialDriver_v2_2_18.dmg file.
- Double-click on it and select the driver file that matches your OS version.
- W ait for it to install and click Close.
- Open the Arduino software for a final check.
- Go to Tools -> Serial Port and look for the USBserial option.
If you do not know the version of your OS, click on the Apple icon in the top left corner of your screen, and select About This Mac.
We hope you managed to fix the Arduino port not showing up issue with our solutions.
