If you swap boards and do not refresh the USB Device Filter on the VirtualBox UI, the ID might be stale and the Docker instance may not be able to see the board correctly. For example, you may see an error message like `Error: unable to find CMSIS-DAP device` when you try to load or run an image on the board. In that case, you need to click on the USB link in VirtualBox UI, remove the existing USB Device Filter (e.g. "Atmel Corp.
