I have searched this site and not found an answer, although this seems to be a similar question: https://devzone.nordicsemi.com/f/nordic-q-a/41853/usb-driver-install-fail-on-window-7-8-nrf52840-nordic_cdc_acm-inf/165534#165534
I am using an nRF52840-based dongle from Fanstel. I have my software working reasonably well (loaded correct firmware, using code calling pc-ble-driver on Windows to talk to the dongle). However, the only way I've found to get drivers is by installing nRF Connect, and that's not a reasonable approach for installing on thousands of end-user computers. I want the same drivers that nRF Connect installs, but standalone, without installing nRF Connect.
I need these standalone drivers for Windows 7 and Windows 10, and Linux.
I thought the files in this location might be the right drivers: https://github.com/NordicSemiconductor/pc-nrfconnect-core/tree/master/build/drivers/dfu_trigger_and_cdc_acm
However, when I try to select them as the driver for the dongle, Windows says “Windows could not find driver software for your device.”
