Uploading to new Uno

kirkr · October 27, 2021, 11:14pm

I just purchased an Arduino Uno. It's my second one. When I plug it in to the USB port the "L" LED starts flashing. On my other board this LED comes on but doesn't flash unless a program is being uploaded. I tried uploading the Blink program as a test and received an error message:" An error occurred while uploading the sketch avrdude: usbdev_open(): did not find any USB device "usb" (0x03eb:0x2104) avrdude done."

I tried a new USB cable with no success and went back and uploaded Blink to my other Uno board without a problem.

I am using Windows 8 on an HP Pavilion laptop.

I have pasted the verbose output from the upload attempt. I have attempted three times. Thanks. Kirk

Arduino: 1.8.13 (Windows 8.1), Board: "Arduino Uno"

An error occurred while uploading the sketch

johnwasser · October 28, 2021, 1:43am

Did you select the right port in Tools->Port: (just below Tools->Board:)?

in0 · October 28, 2021, 1:49am

I can see from your error and output that you did an "Upload Using Programmer". Upload Using Programmer process is triggered by doing one of the following:

Selecting Sketch > Upload Using Programmer from the Arduino IDE menus
Holding the Shift key while clicking the upload button in the Arduino IDE
Pressing the Shift+Ctrl+U keyboard shortcut

If you don't have a dedicated ISP programmer hardware connected to your Uno (and you would know if you did), then there is no chance "Upload Using Programmer" will work. It won't do any harm, but it's a waste of time and confusing, so don't do that.

Please try again with a standard upload, which you can do by selecting Sketch > Upload from the Arduino IDE menus.

kirkr · October 28, 2021, 10:24pm

Thanks for your assistance. I apparently have a very weird problem here. I tried your suggestion. With the Blink file open I used the menu bar item Sketch/upload and received the same message:

avrdude done. Thank you.

A couple questions
Should the On Board LED be blinking after I plug in the USB cable?

Also at the end of the error message it said the overriding baud rate is 115200

Is that an issue? Thanks. Kirk

Hi John,
I checked the Tools menu and Port is greyed out as in not active.
Not sure what that means. Maybe I need to reset something.
I will check the Arduino installation procedures. I welcome any suggestions!

kirkr · October 28, 2021, 11:00pm

Regarding Ports, I opened Device Manager and located Serial Ports (with the UNO plugged in). It showed the UNO connected to COM 4. I went back to the Blink program toolbar and COM 4 was displayed. I tested Upload and it worked this time. I'm not sure what I did. I'm assuming the Arduino software made the connection once I went to Device Manager. I had been using COM 3 all this year. Thanks again for the tip! Kirk

lwin12 · October 28, 2021, 11:02pm

Make sure you check if the selected port is the same as the one that display in your device manager

kirkr · October 28, 2021, 11:02pm

Update, another user suggested checking the Ports on the Blink program. Somehow the ports were altered and needed to be reset. Thanks for your ideas. Kirk

in0 · October 28, 2021, 11:23pm

It was not the same. There are many possible causes of a compilation or upload error. The error messages can be somewhat cryptic and there is a lot of output, some of which you will get even during a successful operation, so it can be difficult to determine which part to focus on. In this case, it was here:

I recommend that you do this:

Select File > Preferences from the Arduino IDE menus.
Uncheck the box next to "Show verbose output during: [x]Compilation".
Click the OK button.

The verbose compilation output is very verbose and most of the output is not at all useful to the normal user on a daily basis. It is more useful for troubleshooting problems with the Arduino IDE itself, rather than problems with your own code or board. You might enable it temporarily as needed if you are having a strange compilation failure or if you get curious to learn more about what the Arduino IDE does during a sketch compilation.

I recommend always leaving the verbose upload output enabled because there isn't so much of it and even when the upload is working fine it provides some nice visual feedback about the progress of the upload.
