You can use the&nbsp; <a href="https://github.com/NordicSemiconductor/nrf-udev">nrf-udev</a> package to get user access.</p> <p>Also, there is a bug in the Segger VCOM implementation that may require you to disable the mass storage class. Please check out this link for more details: <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/guides/tools/nordic_segger.html?highlight=msddisable#disabling-the-mass-storage-device-functionality">https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/guides/tools/nordic_segger.html?highlight=msddisable#disabling-the-mass-storage-device-functionality</a></p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
