Check that it shows up in device manager when you connect it.Eso es lo que no he podido solucionar la conexión del VIM y si estoy usando el adaptador mini-vci j2534
If you are using a Virtual machine, the XP one at a guess, you should hear it make an audible sound when you connect, and it should also appear in the XP device manager, without any errors or yellow exclamation marks.
If that all looks good, and you have tried all USB ports, it might be worth trying it with another PC.
