here 2 jars in manifest file, , sure x86_64 lib in project;

 lib/mail.jar   lib/gson-1.6.jar   lib/usb4java-1.2.0.jar   lib/libusb4java-1.2.0-linux-x-86_64.jar   conf/

any 1 had similar problems usb4java. silly have missed.

thanks

maybe typo. if you're sure jar natives on classpath, may in manifest file wrote: libusb4java-1.2.0-linux-x-86_64.jar instead of libusb4java-1.2.0-linux-x86_64.jar
