Arduino Duemilanove showing up as libusb in device manager

I'm aware that this is a recurring topic in this forum but I can't find a solution that fixes the problem, at least for Windows 11. My Arduino shows up in device manager as a libusb

I've tried installing the most recent FTDI drivers, uninstalling ande clean installing again the IDE, used different USB ports.

Is it an official device? Some of the non-official devices use the CH340 chipset which will require additional drivers.

Hi @lafxxer. For some reason the inappropriate "libusb" driver is installed for the board. The driver we need is the FTDI driver.

Please try this:

  1. Connect the Duemilanove board to your computer with the USB cable.
  2. Open the Windows Device Manager.
  3. Select View > Devices by type from the Device Manager menus.
  4. Open the "View" menu.
  5. If there is a ✓ to the left of the "Show hidden devices" menu item, click on "Show hidden devices" to disable it.
  6. Find the problematic device in the Device Manager tree
  7. Right click on the problematic device.
    A context menu will open.
  8. Select "Uninstall device" from the menu.
    The "Uninstall Device" dialog will open.
  9. Check the "Attempt to remove the driver for this device" checkbox.
  10. Click the "Uninstall" button.
    The dialog will close.
  11. Disconnect the USB cable of the board from your computer.
  12. Connect the board to your computer with the USB cable.
  13. Wait to see if the problematic device appears once again. If so, repeat steps 6-13 again until the problematic device no longer appears.
    ⓘ I believe it is necessary to do this multiple times in cases where multiple installations of the "libusb" driver have been made for the device.

After doing that, hopefully Windows will install the correct FTDI driver for the board and the Duemilanove should then be recognized as a COM port and be usable with Arduino IDE.
