:lastproofread: 2021-07-07 .. _information: *********** Information *********** VyOS features a rich set of operational level commands to retrieve arbitrary information about your running system. ######## Hardware ######## .. _hardware_usb: USB === 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 recent Linux distributions.
