Does a flatbed scanner with these features exist?

Hello, I have done some searching and not found anything... I hope you don't mind this question.

I am looking for a flatbed scanner that has:
- CCD sensor, not CIS
- USB as power source, not AC
- the ability to be used with current Mac OS
- the capability of fairly high resolution (so not the neat little battery powered 4x6 model that sadly only goes to 600dpi)

Does something like this exist?

Thanks for any help!

As a film scanner and not just documents? If so no.
For film scanning I suppose you could use a digicam.

Thanks for the reply, Les, and sorry I missed that detail in my list -- this would be for reflective material scans, not for film.
