Has anyone been successful in interfacing a PIC16, a MAX3421 USB Host and a camera?

Actually, if all you want to do is control the shutter remotely (or an external intervalometer), there's an easier way to do this. I dont have a Nikon, I use Canon, but the principle is the same.

Unfortunately, the Nikon D40 only has a USB interface, so USB commands are the only option.

How about IR, then?

Well written code running off NiMH batteries should go on for quite a few days without a recharge, I guess. Still much simpler than USB, I'm sure.

I actually started down the IR path several months ago, by buying another IR control to modify.

My MAX3421 Eval kit arrives today, so I will be able to experiment with USB control. Who knows, I may go back to IR soon.

This might be helpful although not directly answering your question. I went searching for a 3.3V to 5V converter and stumbled on to it.
