USB Device Enumeration

This sample enumerates the connected USB devices and provides information about the interfaces and endpoints.

Prerequisites

• Java 19
• Apache Maven
• 64-bit operating system (Windows, macOS, Linux)

How to run

Install Java 19

Check that Java 19 is installed:

$ java -version

If not, download and install it, e.g. from Azul.

Install Maven

Check that Maven is installed:

$ mvn -version

If it is not present, install it, typically using package manager like Homebrew on macOS, Chocolately on Windows and apt on Linux.

Create the java-does-usb library

Since the java-does-usb library is not yet available on Maven Central, it must be built locally:

$ cd JavaDoesUSB/java-does-usb
$ mvn install

The result will be put in your local Maven repository.

Run the sample

$ cd JavaDoesUSB/examples/enumerate
$ mvn compile exec:exec
