Unable to upload to Uno R4 Minima

[nea_snow]

I have gotten my hands on an Uno R4 Minima board and am struggling to upload sketches to it. I am able to on a separate Windows 10 computer, am unable to on my Windows 11 laptop. On the laptop I consistently get the following error message whenever I try and upload a sketch:

Cannot open DFU device 2341:0069 found on devnum 1 (LIBUSB_ERROR_NOT_FOUND)
No DFU capable USB device available
Failed uploading: uploading error: exit status 74

Under "Other Devices" in the Device Manager I see this:

So I believe there is something wrong with my drivers but I cannot manage to fix it regardless of what tools I use. Any advice would be amazing.

Yes, you have to get out of DFU mode. Here are the instructions.

If the board is in DFU mode but still detected by your computer (usually as a USB device called “Arduino UNO R4 Minima (DFU)”), try this:

1. Open the Arduino IDE (version 2.x recommended).
2. Go to Tools > Board , and select Arduino UNO R4 Minima .
3. Go to Tools > Port, and select the DFU port (if available).
4. Open a basic sketch (like Blink) and upload it.

If successful, uploading a sketch will exit DFU mode automatically.

Here is another way

Method 2: Double-Reset Trick

If the board is stuck or unresponsive:

1. Press the Reset button twice quickly.

• This attempts to put the board into the bootloader.
• You may see a different USB device show up temporarily.

2. Then upload a sketch immediately .

Timing can be tricky—try a few times if needed.

Confirming It’s Out of DFU

Once it’s out of DFU mode, it should:

• Show up as a normal serial device (like /dev/ttyACM0 or a COM port).
• Be uploadable from the Arduino IDE without any DFU indicators.

When plugged in the device shows as:

I tried both methods a few times but continue to get the same error as before. In the bottom right corner of the application it reads "Arduino UNO R4 Minima on COM3" outside of bootloader and the same with "[not connected]" at the end when bootloader is active.

I am unable to find a USB device named “Arduino UNO R4 Minima (DFU)” in device manager when I plug it in the three things that appear are both objects in the image below as well as a "USB composite device" under Universal Serial Bus controllers.

[sonofcy]

You should read the documentation for the board. It can be used in one of two modes, normal and DFU. Somehow, your board got switched from normal to DFU. I gave you the instructions to get out of DFU. I left out the parts you should already know, like restarting the IDE, possibly rebooting Windows, although unlikely.
Show me the screen when you do procedure 1, then procedure 2. Don't forget to restart the IDE and Windows after each one. If it is still stuck, there is a 3rd way, but it is more technical and requires the command line and UNIX commands (yep, there is UNIX inside Windows)

[nea_snow]

Procedure 1:
Open Arduino IDE & plug in Board.

Tools, Board, Select Arduino Board.

Tools, Port, Select COM3 because DFU is not an option

Upload Sketch & error.

Procedure 2:
Quickly double-press the reset button to enter bootloader, the orange LED starts to fade in and out, quickly press upload & error.

Other Computer
Unplug USB from laptop, move over to desktop, plug in, select board, upload a sketch & it works.

I believe the errors happen because of some configuration setting on my laptop or drivers. I do not understand why I keep getting the error when the device appears as a normal com port via method 1, and works on the desktop perfectly fine.

[sonofcy]

The last screen shows it worked in DFU mode. Use that computer to try to get it to normal mode.
No configuration on the laptop or drivers involved; that board is one of a few that have this duality that I hate.
Since you obviously have not read the documentation, I am moving on and will leave you to 'play'.

[nea_snow]

You are correct, I have not read the documentation about this topic, I don't know where it is. All I can find when I search for my issues are forum posts so I thought to make one. If you could share a link a link for where I can go to read and teach myself, it would be appreciated.

[sonofcy]

It's all here on the Arduino.cc website. If you are new to the layout and navigation, it can be confusing. But before I go on, have you noticed that at the bottom of your thread, there are suggested posts that may help. It looks like the following. Maybe more than one, check them out.

Before I show you where the docs are, let me point out that many have criticized the quality of the docs. I find them sometimes excellent but often strangely organized and sometimes horrible.
Here is the big picture. At arduino.cc you will see, then select Documentation and see now click on Go TO DOCUMENTATION (or Hardware). I am sure you can figure it out from there.

then select

[sonofcy]

Sorry, I think some screen grabs are in the wrong order.
Big picture is go to web site with weird format arduino.cc
You will see this

Click on Documentation and you will see the following

Now click either GO TO DOCUMENTATION or Hardware.

I was so happy with R3 ARDUINO but now R4 i get only problems! UNO R4 and NANO R4 get no connection to two different Laptops. I Try everythink what is here in forum: 2 time reset / unisnstall install IDE = nothing helps! For what do i purchuse this new R4? Back to the simpy R3 that is all the time working!

[ptillisch]

Hi @ebookaktiv.

@ebookaktiv

UNO R4 and NANO R4 get no connection to two different Laptops.

I'm not sure I understand what you mean by this. Please provide a detailed description of what you mean by "no connection in a reply here on this forum topic.

If you are seeing any warning or error messages associated with the problem, please include the full and exact text of the message.

[ebookaktiv]

I get the answer ERROR 74 every time

[ebookaktiv]

I have connection to UNO R3. When i connect NANO R4 than i get:

No DFU capable USB device available
Fehlgeschlagenes Hochladen: Hochladefehler: exit status 74

Tools = Board : Arduino Nano R4
Port: i see some COM but no one with NANO R4

What to do?

[ptillisch]

Thanks for the clarification. I'm going to ask you to provide the full verbose output from an upload attempt.

---

This procedure is not intended to solve the problem. The purpose is to gather more information.

---

Please do this:

1. Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
   The "Preferences" dialog will open.
2. Uncheck the box next to Show verbose output during: ☑ compile in the "Preferences" dialog.
3. Check the box next to Show verbose output during: ☐ upload.
4. Click the "OK" button.
   The "Preferences" dialog will close.
5. Attempt an upload, as you did before.
6. Wait for the upload to fail.
7. You will see an "Upload error: ..." notification at the bottom right corner of the Arduino IDE window. Click the "COPY ERROR MESSAGES" button on that notification.
8. Open a reply here on this forum topic by clicking the "Reply" button.
9. Click the <CODE/> 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.
   
   
10. Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
    This will paste the error output from the upload into the code block.
11. Move the cursor outside of the code block markup before you add any additional text to your reply.
12. Click the "Reply" button to publish the post.
