No DFU capable USB device available

Software Web Editor
1

I'm trying out the new Minima Uno R4 using the Web Editor on Windows 10. The web editor detects the device and port automatically, but when I try to upload I receive the error:

"Cannot open DFU device 2341:0069 found on devnum 6 (LIBUSB_ERROR_NOT_FOUND).
No DFU capable USB device available"

When I connect an older UNO R3 it is detected automatically, and I am able to successfully upload to the R3.

When I connect the new UNO R4 WiFi it is detected automatically, and I am able to successfully upload to this board.

I would love some troubleshooting advice on why the Minima board is not able to upload. Thanks!

Could you try installing the drivers according to your OS? https://github.com/arduino/ArduinoCore-renesas/tree/main/drivers

I did not follow your suggestion because I had already found a solution. I uninstalled and reinstalled both the Arduino Create Agent, as well as the Arduino IDE (as well as deleting all of my libraries). After reinstalling the software I was able to successfully use the Web Editor with the Minima.

Thanks for you help.
