Is there a Windows driver for the nRF52840 USB CDC ACM?

[Roger Clark]

Hi

I'm trying to use the nRF52840 USB Serial UART device (aka USB CDC ACM) however I can't find a Windows driver for this device

The VID is 0x1915 and the PID is 0x520F

I've looked in all the development files listed for the nRF52840 PDK www.nordicsemi.com/.../nRF52840-Preview-DK

But I can't find a driver.

I've tried forcing a CDC ACM driver using libwdi, but although the board then appears as a serial device, I can't see any data from the board, so I presume that method is not valid as it may be a composite device and i need a more complex install method (or the official driver)

Hi. You can find "nordic_cdc_acm_example.inf" file in the project folder. Try to use it through "Device manager"

Thanks.

I found and tried using that file but I just get

"Windows was unable to install your nRF52 USB CDC Demo"
