systeminformation

USB

In this section you will learn how to get information about detected USB devices:

For function reference and examples we assume, that we imported systeminformation as follows:

    const si = require('systeminformation');

## Detected USB Devices

All functions in this section return a promise or can be called with a callback function (parameter cb in the function reference)

Function | Result object | Linux | BSD | Mac | Win | Sun | Comments
--- | --- | --- | --- | --- | --- | --- | ---
si.usb(cb) | [{...}] | X |  | X | X |  | array detected USB devices
| [0].bus | X |  |  |  |  | USB bus
| [0].deviceId | X |  |  |  |  | Bus device ID
| [0].id | X |  | X | X |  | ID e.g. 0bda:8821
| [0].name | X |  | X | X |  | name, e.g. root hub
| [0].type | X |  | X | X |  | type e.g. keyboard or mouse
| [0].removable |  |  | X |  |  | is removable
| [0].vendor | X |  | X |  |  | vendor e.g. Realtek
| [0].manufacturer | X |  | X | X |  | manufacturer e.g. Chicony
| [0].maxPower | X |  |  |  |  | max power e.g. 100mA
| [0].serialNumber | X |  | X |  |  | serial number if available
| ##### Example
    const si = require('systeminformation');
    si.usb().then(data => console.log(data));
