The latest release of ufraw doesn’t support Canon EOS 1100D, but the support code is present in their CVS repository. To compile ufraw with support for EOS 1100D, I patched following files from ufraw CVS repository: dcraw.cc, dcraw.h, and wb_presets.c, and rebuilt it. And, now ufraw is able to recognize White Balance information from camera.
