swestin, if you have trouble, I have THAT camera. I'm just
still clueless about Canon native protocol. Contact me if
needed.

I actually have a 20D on my desk right now. Unfortunately, its
protocol is a major alteration of what has gone before: some
command codes are the same, some have been reassigned to
new functions, and there are at least seven new ones!
I'm working on it at low priority.

I can probably help. Where can I getr the command code
documentation from?

Well, there is a DocBook XML file
libgphoto2/camlibs/doc/Protocol.xml. If you have as much
hassle as I do turning that into readable HTML, point your
browser to http://www.graphics.cornell.edu/~westin/canon/
which is derived from it. The latter is actually updated more
frequently as I learn more about the 20D.

I get different errors. swestin removed support for it in
gphoto2 until we fix it.

I don't know if it can help, but i have tried to connect my
20D with gphoto2 under a 10.1 mandrakebox with rpm from cooker.
It doesn't work, it's not a scoop, but what i don't
understand, is it doesn't send any error to me, it's just it
says that there is no file in any directory, or there are !
i connect in PTP mode, (normal mode doesn't work) after
having changed into the camera the configuration item to PTP
mode with this command line :
gphoto2 --camera "Canon EOS 20D (PTP mode)" --port
"usb:002,010" -l
that gives :
"Il y a un dossier dans le dossier '/' :
- store_00000001
Il n'y a pas de dossier(s) dans le dossier '/store_00000001'.
"
when i try to get file list it say there is non files ...
I can send you the debug file if it can help, but i really
don't understand a word of it ;-)
thanks for your work till now

PTP != Canon mode.
PTP problems have been addressed for the upcoming 2.1.6.

The eos 20d will work in PTP mode already (with current CVS and
starting with 2.1.6).
Canon driver work is still in progress...

For the brave, there is now experimental support for the 20D (and 350D).
Rebuild from CVS with CFLAGS=-DCANON_EXPERIMENTAL_20D and
try it. As far as I know, things are functional except --capture-image under
Linux (works fine under Mac OS X) and thumbnail and info operations.
Thumbnails (from which we get image info) are handled differently for raw
images on these cameras; this will take some time to work out. And I'm
working on Linux image capture.

we have good success reports from the EOS 20D even in normal mode now.
