I would suggest you look seriously at the FTDI part, which is available in two versions, one is USB to serial UART and the other is USB to parallel. Both will take a 93C46 type eeprom for the enumeration info, and can load this eeprom from the USB bus using a utility available on the FTDI website. 40 pin surface mount package, requires 6MHz crystal or resonator, possibly driven from external clock if this already available IIRC, it is a while since I looked at the data sheet. Check out http://www.ftdichip.com/ and make sure you pick up the B versions of the chips. The "get out" clause. I don't have experience with any USB chips, but have looked at these with interest. They appear to have some nice features, and there are some app notes on the web page as well. -- http://www.piclist.com hint: The PICList is archived three different ways.
