Programmable/Controllable camera (USB) with Full Focus Control

Any recommendations on digital cameras that can be accessed and
controlled
fully through the remote (USB) port, including full focus control?
Info on
open source C/C++ SDK's would be very helpful too. I am fairly new on
the subject.

Thanks,
Ben

I am not aware of any digital camera driver with focus control but why not
use a CCD camera?
Fingerlakes makes some all right cameras and the source-code
availab driver can be compiled (and works) at least with Linux. I have
not tested the BSD or Win version of the drivers. focus control could be
achieved with a tiny additional program which reads the frame, does a
Gaussian and tries to adjust the focus depending on the FWHM change
(minimising the FWHM in both perpendicular axis).
