Answer 1

Have you created the javax.usb.properties file ? If not you need to create it, you put it in the folder with all your others files. With inside this file:

javax.usb.services = org.usb4java.javax.Services

Have a look to this tutorial: http://usb4java.org/quickstart/javax-usb.html

Create resource folder

• Right click on Java Resources > New > Source Folder
• At Project name, click Browse button > choose your project name
• At Folder name, enter your folder name as resource > click on Finish button

Create javax.usb.properties

• Right click on resource folder > New > Other > File> click Next button
• Enter File name as javax.usb.properties
• Click on javax.usb.properties to open > write this :

If using usb4java lib

javax.usb.services = org.usb4java.javax.Services
