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)

For me the matter is unsolved also when using latest SDK 13.1. OS is W10. Serial port is installed automatically by using W10 standard driver (usbser.inf). There is a message in the properties event window (device manager/serial ports) saying that more installation has to be done - maybe not important because W10 basically confirms functionality. Nevertheless data exchange is not possible. The .inf file delivered by Nordic is not accepted - W10 misses a digital signature. Could there be an uncomplete set of information inside the USB description records?

I also want to ask for the present state in managing the VID/PID for users of Nordic chips. The typical procedure is that we can use Nordic's VID but will get one or some unique PID's by the vendor.
