Since the introduction of the DiMAGE 7 digital camera quite a few users have tried to make it work with Linux, especially the colour transformation that the (Windows and MAC) software by Minolta performs.
To make it easier to search for information, I've made a small list of software that's available:

The GIMP Dimage color plugin

This plugin, by Laurent Houdard, is for the Gimp where performs the same colour transformation as the DIVU (DiMAGE Image Viewer Utility) from Minolta.

After installation it can be found in the Image -> Colors menu. Homepage is http://dimage-color.sourceforge.net/.

MRWtoPPM

To convert the raw files from the DiMAGE 7 into PPM files (Pixmaps which can be converted to all kinds of formats) Bradley Broom has written MRWtoPPM, including colourspace conversion and interpolation.

The homepage can be found at http://home.swbell.net/dobroom/mintoppm/.

USB patch for Linux

The DiMAGE 7 does not work out of the box with the standard Linux USB driver. The camera is seen, but disconnects as soon as you try to mount it.

Kedar Petankar wrote a small patch for this problem, for kernel version 2.4.17. He has submitted it to the USB maintainer, so it may get into the mainstream kernel. Matthew Geier added information about the DiMAGE 7i and Mikael Lofjärd sent an update for the 7Hi. When cleaning up I found an update from Rob Reid for the s414.. it has also been implemented. Thank you all very much for the updates!
Until all information is in the kernel, I have put it in a small file, which you can put into drivers/usb/storage/unusual_devs.h in your kernel source directory.

UPDATE: From the third version (with the addition of the DiMAGE 7Hi), the file can no longer be merged with unusual_devs.h using patch, but you have to add it manually. Please look for the string 'Minolta' in the file and put the patch between these two entries (they are for the S304 and 7, although they both say S304). The reason for this change is that the location where the patch needs to go changes in every kernel version, and patch would always put it in the same location, even if this would be inside of another entry...
