Just a few things... Is the protocol used by the PC-application published ? Or how are you going to know how to "control" the camera ? Even if you're able to get something like an USB host running. And, as you might have found out by know, USB was designed to have it "host" on something not less capable then a Windows PC (or similar)... Doesn't the camera have some wireless (IR probably) remote ? That one would/could be easier to emulate.
