NXT Communication

[NewDev]

Hello,
I work on a school project, it's an application using Javascool (http://javascool.gforge.inria.fr/ (in french)), a french project, and my part of the project is to create an application who could remote the NXT. The bluetooth connection currently work but not the USB connection... For the Bluetooth connection I used "Bluecove" and it worked perfectly, I was thinking with "pccomm" it will work similary but not.
To explain you how my application work, it's simple, I put for exemple the "bluecove" in the folder which will be build by the compiler included in Javascool and it work.

Sorry for my english and thank you for your help.
