Does anybody know how to implement the usb api. i downloaded the files for java usb api. but i dont know where should i store this files in order to type command like "import javax.usb.*" Morever is there any alternative approach to get the data out of the usb. any help will be greatly appreciated. I have been pointed to links before but links do not have explanation for how to and where to store this files and how to implement them. I found a website which talks about similar stuff..
