This could be true, or it could be that the Slackware 14.2 libraries are too old, or the camera is using an odd version of MTP, or the USB port is too slow. You can also try a different USB port - not all are created equal. Canon cameras are supported via gphoto. Slackware has libgphoto2-2.5.10 and gphoto2-2.5.10 that support the Canon Rebel T3 (no EOS?) http://gphoto.org/proj/libgphoto2/support.php try: $ gphoto2 --auto-detect signature.asc Description: OpenPGP digital signature ___ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
Re: [PLUG] Communicating with digital camera via USB
Please tell more - I cannot see how a card reader in a form of digital camera can do something not exploitable with the card itself.

Because, because, because it became an exploit, and that is why we can't have nice things.

Re: [PLUG] Communicating with digital camera via USB
Just thinking of fiddling with DSLR over USB makes me tired - I do not even try anymore - use card reader - it is faster and trouble free. Once upon a time - I owned Fuji camera which presented the card as USB masstorage. That was joy to use on any device. If I remember correctly, I could even boot PC for fun from the camera. I keep asking myself why, why, why,... can't just everybody do that.

[PLUG] Communicating with digital camera via USB
I have a Canon EOS Rebel T3 digital camera and just purchased a USB cable that is supposed to work with this model. When I connect the camera to a USB port on the desktop /var/log/messages reports: Jun 23 08:05:32 salmo kernel: [1090432.979576] usb 1-14: new high-speed USB device number 60 using xhci_hcd Jun 23 08:05:32 salmo kernel: [1090433.187069] usb 1-14: New USB device found, idVendor=04a9, idProduct=3217, bcdDevice= 0.02 Jun 23 08:05:32 salmo kernel: [1090433.187070] usb 1-14: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Jun 23 08:05:32 salmo kernel: [1090433.187071] usb 1-14: Product: Canon Digital Camera Jun 23 08:05:32 salmo kernel: [1090433.187072] usb 1-14: Manufacturer: Canon Inc.

My web searches for how to use the Canon USB cable with linux found only one unanswered question from a couple of years ago. I can always return to removing the SD card and using the card reader but I assumed I could do direct downloads. Your thoughts and suggestions are solicited.
