Find USB device details in Linux/Unix using lsusb command. Today we will see how to list USB devices in Linux and their properties such as speed, BUS, class, type details etc. This is part of our on going hardware detection series. We already covered following stuff. Get BIOS, Firmware, Hardware And Drivers Details in Linux/Unix.

What is dmesg command and how to use it in Linux/Unix? Find hardware info with lshw, hardinfo, sysinfo Linux/Unix commands. Find PCI hardware details using lspci command in Linux.

USB(Universal Serial Bus) is a stranded developed to replace different types of BUS’s available. This is a solution devices to eliminate vendor lock- down of hardware ports, so that BUS’s will be identical across different devices from different vendors. USB devices solve one more problem i. USB devices can reach up 5. GB/s as of this writing where as PCI and serial devices have less speeds. Depending of USB firmware, it’s categorize in to USB 1.

USB 2. 0, USB 3. 0. USB have competitor in the from of Thunderbolt interface. As a Linux User/administrator we should know USB bus details as well as devices connected. In this post we will see how to use lsusb command to display different USB properties. Example 1: List all the USB ports availablelsusb. Output:Bus 0. 01 Device 0.

Example 2: Check how many USB ports available in your machine so that we can connect USB devices to these ports. Output:/dev/bus/. These ports may be internal or external to the system. Example : Get detailed information of a USB device connected to a machine. Suppose I want to see information about /dev/bus/usb/0. D /dev/bus/usb/0.
