Hot diggity. Took a bit of time to get it going but this Z740, a brand new model (as of March 2005) does work under gtkam as a USB PTP Class Camera, per previous reports of what to use with these newer EasyShare digital cameras. This model came with the EasyShare Printer Dock Series 3 and the camera was docked with the USB connected to the printer/dock (not the camera). You have to push the button with the computer icon on the dock and turn on the camera to get the communications going and gtkam should detect it at some point (the dock icon will start blinking when something is happening). Some of the other Linux camera programs will eventually detect as well (eg., Kamera & Digikam). It took a bit to get the communications going but it did finally get going and I could transfer pictures over to my PC running Suse 9, using gtkam.

The Z740 also works under gtkam as a USB PTP Class Camera. It isn't necessary to use the EasyShare Printer Dock or EasyShare Camera Dock, the included USB cable works fine. Just get gphoto2/gtkam set up (permissions and all), connect the cable, and turn on the camera. Gtkam will be able to detect it.

Could not get this camera working right using the USB connection (haven't got a docking station to try) on Mepis Linux 3.4.2. I'm using the latest gphoto2 and libgphoto2 (currently 2.16-6) from the debian repos.

When connected, the camera will sometimes connect and download thumbnails, but it will not allow me to download the photos themselves. I tried it under gtkam, digiKam, and gphoto2. At the terminal, I get a response something like this:

"ptp error, response expected" (exact wording may be a little different). I've tried to fix this problem with some of the setup instructions on the gphoto site but had no luck. It worked one time, but I couldn't get it working again.

Hope this gets fixed soon, I think this will likely be a popular camera!
