1. Install Linux On Usb Drive

If your data center relies on VirtualBox and your virtual machines rely on USB, you've probably noticed that USB doesn't work unless you enable it. Here's how to do that.

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.

What is USB?

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.e. speeds. USB devices can reach up 5GB/s as of this writing where as PCI and serial devices have less speeds. Depending of USB firmware, its categorize in to USB 1.0, 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 available

Output:

Let us try to understand above output in detail.

Bus 002Device 003: ID 0781:5567SanDisk Corp.Cruzer Blade

Bus 002 : This is bus number where SanDisk USB stick is attached.

Device 003: This is the third device attached to bus 002, the other two devices are “Linux Foundation 2.0 root hub” and ” Intel Corp. Integrated Rate Matching Hub”

ID 0781:5567 is the number given to this SanDisk, The number before : indicates the manufacture ID and number after : indicates device ID. To get more info on this visit Linux-USB site.

SanDisk Corp. Cruzer Blade is the name of manufacture and device name.

Example 2: Check how many USB ports available in your machine so that we can connect USB devices to these ports.
