Windows Vista & Canon 20D problems

OK..I am really getting frustrated with all the downloads I have had to do with this new Window Vista. I have gotten everything to work except for my Canon 20D. Windows Vista will NOT even recognize that I have plugged the cable in & turned the camera on. It isn't listed on the My Computer screen. I have gone to Canon.com & downloaded what it told me to download & still nothing. I also have a problem that when I do plug the camera in & turn it on it "boots up" my scanner toolbox. The only options on my scanner toolbox is for copying &scanning...there is no options for opening my camera. Can you help? OH...I have Windows Vista 32 not that 64. I noticed they have no download for the 64. Both discs I received with my camera were both installed. I also want to note that I have a Canon PowerShot A570IS that I haven't even put the software into the computer & it is accepted...but the 20D is not..

Any help would be greatly appreciated.

Set the D20 camera communications setting on PTP instead of NORMAL. Vista will then recognize it as a device and give you more options for starting up transfer software. Windows Photo Gallery will handle jpg file transfers.

I am glad I found this forum and your solution to change communication to PTP worked for me as well. Oddly, the camera's manual specifically states that PTP is NOT for download to a PC, that it does not work. So much for that. I have always used a card reader but went through 2 in the past 7 uses with bent pins (one melted and could have caused a fire) because they are engineered so poorly they don't line up cleanly, at least in my opinion. I will continue to search for a good one though, prefer that to doing the direct camera download.
