Yes, great idea, Riccardo -- please do it. :-) However, there is no standard for accessing digital photo cameras via USB. Recently, some of them seem to comply with the mass storage protocol (BSD's umass driver), but the majority of them use proprietary protocols. Even the same vendor uses different protocols for different of his cameras. So, basically you would have to write a separate kernel driver for every camera. This isn't feasible. It is probably much better to handle these issues in userland code. As an example, you could have a look at the "oPhoto" tool which handles the Kodak DC240, DC280 and DC3400 under Free- BSD (and possibly also others, but _not_ the Kodak DC220, DC260 and DC265). These are all USB photo cameras. The tool is written in userland code and uses the generic ugen driver to access the camera, which works pretty well. If you absolutely want to access the images like a real filesystem (I don't think this would have any real advan- tage), you could wrap an NFS userland server around the code. Bloating the kernel with such stuff is a bad idea, IMO.
