I installed the Arduino IDE 2.3.2 and the UNO R4 Board extensions on two different PC's.
The Board R4 Minima is correct recognized (via Tools/Board information).
After compiling the scetch (with CAN receiver functionality and serial output) it cannot be loaded into the R4 Minima board. A similar error message comes as other users already posted: "annot open DFU device 2341:0069 found on devnum 6 (LIBUSB_ERROR_NOT_FOUND)
No DFU capable USB device available
Fehlgeschlagenes Hochladen: Hochladefehler: exit status 74"
Then i tried to do the double reset with reset button and the yellow led flashes but smoothly dimmed.
Even if i load an *.ISO without can and serial port (simple internal LED flashing) i get this message and i am blocked.
In former project it worked with the R4 WiFi , ESP32 derivates and Uno R3.
I dont know how to download the driver from GIT under:
there i miss the "Download zip" of the driver WIndows 10. Please give me some advice, thanks

Hi @musitron. Arduino IDE automatically installs the drivers as part of the Boards Manager installation of support for the board. However, the driver will only be installed if you provide approval, which is requested via a Windows User Account Control (UAC) dialog that is displayed during the installation:
Do you want to allow this app from an unknown publisher to make changes to your device?
dpinst-amd64.exe
It might be that the driver is missing because you did not approve its installation at that time.
The solution will be to reinstall the "Arduino UNO R4 Boards" platform, making sure to approve the driver installation offer:
- Select Tools > Board > Boards Manager... from the Arduino IDE menus to open the "Boards Manager" view in the left side panel.
- Scroll down through the list of boards platforms until you see the "Arduino UNO R4 Boards" entry.
- Hover the mouse pointer over the "Arduino UNO R4 Boards" entry.
You will see a ●●● icon appear at the top right corner of the entry.
- Click the ●●● icon.
A menu will open.
- Select "Remove" from the menu.
An "Uninstall" dialog will open.
- Click the "YES" button in the "Uninstall" dialog.
The dialog will close.
- Wait for the uninstall process to finish, as indicated by a notification at the bottom right corner of the Arduino IDE window:
Successfully uninstalled platform ...
- Click the "INSTALL" button at the bottom of the "Arduino UNO R4 Boards" entry.
- Wait for the installation process to finish, as indicated by a notification at the bottom right corner of the Arduino IDE window:
Successfully installed platform ...
After you have done that, try uploading the sketch to your Arduino board again, just as you did before. Hopefully it will be successful this time. If not, please let us know and we'll provide further assistance.
The driver files are part of the "Arduino UNO R4 Boards" platform, so they are downloaded to your computer when you install the platform via Boards Manager. If for some reason the automatic driver installation doesn't work, I can tell you where to look on your hard drive to find the driver, but I think letting Arduino IDE install the driver will be the easiest way to go so let's wait to see if the instructions I provided above will solve the problem.
Hi @Ptillisch, Thanks a lot for your detailled instructions and explanations which has been successful. Now after re-Installing the UNO R4 Family Board package the driver has been updated as you described and now it is functional completely.
Thanks a Lot for your effort!

You are welcome. I'm glad it is working now.
