 | |
| In the past serial interface have been defined as ttySx and ttyUSBx where x was
 | |
| an instance number of the serial interface. 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. This
 | |
| somehow mimics the new network interface definitions we see in recend Linux
 | |
| distributions.
