帮后进菜鸟解读INF文件，谢谢

INF文件主要是用在安装的时候吗？我看了DDK文档有关INF的内容，一是英文不大懂，二是新手一个，哪个好心人帮忙解读一下一个实际的例子。如下：

这似乎是个USB-TO-SERIAL的驱动安装信息，在安装完这个驱动后，会多出个COM3口，请帮忙解释一下这个INF文件。谢谢 :(

自己看一下walter oney的Programming the Microsoft Windows Driver Model吧，里面有inf文件每个域的详细解释。

重申：本人是菜鸟，但不是懒鸟。资料我每天都在看，事实是现在关于驱动的中文资料极少，本人英文又烂，现在挂着词霸也看的累，所以在此发帖求助，各位总不至于跟我说：先学两年英文在来搞驱动之类的话吧 :P

顺便问一句：对于在WIN2000中已有的标准驱动，比如标准MODEM的驱动，如果我想用它，是否只需要写个INF文件就好了？
