Lpc2000

Hi everyone,
I wanted to fabricate a board with the LPC210x that will have USB
connectivity. I have found some simple chips that would definitely do the
job - for example PDIUSBD12 which is a USB interface device with parallel
bus. However, I don't think I would be able to bootstrap the LPC2100 via USB
using this chip. I was wondering if any of you guys had some experience with
USB chips that have more logic and would be able to easily provide means to
bootstrap the chip. I know of USB controllers that feature the
microcontroller on them but I think that that would be an overkill.
Thank you all in advance,
Cheers,
Milos
