It was discovered that from system +boot to system boot the mapping of USB based serial interfaces will differ, +depending which driver was loaded first by the operating system. This will become +rather painful if you not only have serial interfaces for a console server +connected but in addition also a serial backed :ref:`wwan-interface`. + +To overcome this issue and the fact that in almost 50% of all cheap USB to serial +converters there is no serial number programmed, the USB to serial interface is +now directly identified by the USB root bridge and bus it connects to.
