avrdude: ser_open(): can't open device "\.\COM4": The system cannot find the file specified.

Select the COM port of your Nano from the Arduino IDE's Tools > Port menu.

If you don’t know which port is your Arduino, you can find it like this:

Unplug your Arduino board from the computer.
Tools > Port
Note the ports, if any, listed in the menu.
Close the Tools menu
Plug your Arduino board into the computer.
Tools > Port - The new port listed in the menu is your Arduino board.

I've gotten error :Re: An error occurred while uploading the sketch.
here is my code:

#include <Servo.h>
int pot1 = A0;
Servo myservo;
void setup() {
// put your setup code here, to run once:
myservo.attach(0);
Serial.begin(6900);
}

void loop() {
// put your main code here, to run repeatedly:
Serial.println(pot1);
myservo.write(90);
Serial.println(myservo.read());
delay(1000);
myservo.write(0);

Hi,
I have the same problem. The output is the following:

Make sure you have the correct board selected from the Tools > Board menu.

Make sure you have selected the port of your Arduino board from the Tools > Port menu.

Sometimes the port will be labeled with the board name in the menu. Other times it will not. If you don’t know which port is your Arduino, you can find it like this:

Unplug your Arduino board from the computer.

Close the Tools menu
Plug your Arduino board into the computer.

My case may be interesting in that the error output is somewhat different.
I use an official AtMEGA 2560 board with IDE 1.8.9. Everything worked fine until yesterday ( meaning successful uploads for several days)

Of course I still use the good port : COM6 for me (the only one that appears when I connect the board !)

Now I get that same message with windows 10, Linux Debian, two different machines and two different cables :

I am trying with the blink sketch here. I must add that since yesterday I succeeded uploading twice but failed innunmerable times. May it have some connection with recent avrdude updates ?

You need to select the port of your Arduino board from the Tools > Port menu. If you find multiple ports in the menu and don't know which is the Arduino, Try this:

With the Arduino board unplugged from the USB open the Tools > Port menu and note the listed ports. If the Port menu is gray and disabled then that means there are no ports available.
Close the Tools > Port menu.
Plug in the USB cable on the Arduino board
Wait a little while for the Arduino board to connect
Open Tools > Port, the new port on the list is your Arduino board. In some cases it will have the name of the board next to the port name but this doesn't happen with all boards. If the Port menu is gray and disabled then that means your Arduino board didn't install correctly. You may need to install a driver.
Select your Arduino's port from the menu.

jptrol · September 30, 2019, 8:07am

Too bad that the only suggested solution is to select the right port. Obviously my problem is very different with my config :

avrdude: usbdev_open(): did not find any USB device "usb" (0x03eb:0x2104)

Maybe a faulty board ? Strange, since I get the informations from the board through the USB connection.

Your problem is caused by holding the Shift key while you click the Upload button. That causes the Arduino IDE to do an "Upload Using Programmer" instead of a standard Upload. Since you don't have an ISP programmer connected, that won't work, thus the error.

Thank you for your help Pert. Though I can't remember hitting the shift key or clicking the programmer option , the fact is that when I carefully select upload or CTRL U I now succeed every time I try. May it go on !
Thank you again.

This one is really tricky because the output is not providing us with any useful information about the error. Please try restarting your computer. Maybe by some miracle that will fix the problem, or at least cause the output to show some more info.
