I tried to put the files somewhere else, but it did not solve the problem. However, I made some progress : if I run the application as Root, is works perfectly.
So I have two questions : - with the previous version of javax-usb (running on Mandrake 8.1) I did not need to connect as root. Why do I need it now ? - why don't you recommend to put the jarfiles in the jre/lib/ext dircetoy ? Thanks vey much for your help, Aurelien -----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] la part de Dan Streetman Envoye : jeudi 9 octobre 2003 16:04 A : Aurelien Godin Cc : [EMAIL PROTECTED] Objet : RE: [javax-usb-devel] 0.10.1 I don't recommend putting either the jarfiles or the .so in the jre/lib/ext directory. Can you try it with those somewhere else? If that still fails, can you send the detailed output from the error file it mentions at the end? Also, can you send the output when you run it with -DJAVAX_USB_MSG_LEVEL=DEBUG3 defined?
