Monitoring USB communications using usbmon interface

Learn how to monitor USB devices by using the usbmon kernel module together with Wireshark or Tshark.

Summary

With the help of usbmon we have a cost-effective solution to monitor USB communications between the kernel and a hardware device. It is an alternative to hardware USB protocol analyzers for those on a budget or having to do it once. Loading of usbmon kernel module The first step is to load the related kernel module. This can be done using the modprobe command. $ sudo modprobe usbmon Validate if the usbmon kernel module is loaded using the lsmod command.

Lscpu

The lscpu command reports information about the CPU, such as architecture, vendor identification, virtualization features, cache, and even CPU vulnerabilities.

Summary

The lscpu command retrieves information about the the CPU architecture. The sources to retrieve this information include /proc/cpuinfo, pseudo file system sysfs, and available libraries. Examples of information includes: Cores CPUs BogoMIPS Byte order Cache sharing Caches Family Model Stepping NUMA nodes Threads Sockets Virtualization details Vulnerabilities The tool is both suitable for using in the terminal and manual interpretation, but also for automated processing. When its output is piped to other another application, it is aware that any screen markup should be left out.
