https://devzone.nordicsemi.com/f/nordic-q-a/43694/usb-cdc-acm-bare-metal-exampleHi, I am developing a timing critical application for the nRF52840&#39;s and would like to implement USB functionality as well as be able to turn it on and off in software. Is there a bare metal example somewhere that does not use an RTOS or an API?
