Hello,

I built my application to a single JAR file, and it works as expected in Windows 7/8, and Mac (mountain lion). However in Ubuntu 15/10 I see the devices with lsusb, but I cannot get them from the Java code. I suspect this a dependency issue. Libusb is installed in a non standard location, so I created a symbolic link like this: /usr/lib/libusb.a -> /usr/lib/i386-linux-gnu/libusb.a

I don't have any more clues to solve this...

Note java installed: java version "1.7.0_85" OpenJDK Runtime Environment (IcedTea 2.6.1) (7u85-2.6.1-5) OpenJDK Server VM (build 24.85-b03, mixed mode)

Please help me. Thanks.

You need to set udev rule for your device, or else your user has no access to devices. In ubuntu you are running as non-privileged user, access to hardware needs to be permitted... Google "udev rules ubuntu"

Thanks @andyrozman. The README file provides the details you need @xgonc.
