Re: [pyusb-users] "No backend available" error on mac OS 10.6
Ok, try to create another env variable: export PYUSB_DEBUG_LEVEL=debug And send the results. PyUSB will start to dump debug messages on the screen.

I am having some trouble with the pyusb module. I have narrowed down the problem to a single line, and have created a small example script to replicate the error. I have tried building the libusb module (directly from source AND through macports) for 32-bit (i386) instead of x86_64 (default for OS 10.6), but I receive the same error.

The Neural Network manager for NXT is a Java Graphical User Interface which allows Lego fans to easily create, manage and train a neural network which can be exported and used in any program to be designed to run on the LEGO NXT. The total system comprises of two main parts, a UI running on the NXT and the Neural Network Manager running on the PC. The Neural network is created by the Neural Network Manager and can once trained be exported to a Java file that should be compiled and uploaded to the NXT. The NXT side of the system handles the I/O with the sensors (in our application the LEGO Sound sensor) and the communication with the PC.
