Lpc2000

I would like to use CDC USB class to replace RS232 interface for a 
product implemented with LPC2148.

I have some (mostly "windows") questions:

1. Does microsoft provide standard INF file for the CDC driver?
2. If not, is it possible to define inside INF file the port number 
(e.g. COM9, COM27 etc..)?
3. Where is "normally" usbser.sys after WINxxx installation?



I am sorry for going slightly offtopic, but it's related to LPC214x.
