Thanks to everyone for your replies. I tested everything : cable, usb port etc... with no results. In the end, I had the idea to remove gphoto2 and re-install. No success at all. Next, I did again remove gphoto2 as well as libgphoto2-6... and I re-installed both... Then, gphoto2 did work again !! (just as previously, that is, it only works after 2 or 3 dead trials, the dead times gphoto2 reckognize the camera but gphoto2 -L fails to work)...Bernard wrote:Gphoto2 no longer operates on Debian 11 ever since recent update, same problem on other laptop on Debian 12. gphoto2, for many years, was my tool for downloading image files (RAW, JPG…) from my Canon EOS 600D camera.

I also have a laptop that used to run an old Ubuntu, on which I recently installed Debian 12, to the same result concerning gphoto2 : it used to work on old Ubuntu, not any more on Debian 12 After having run $ gphoto2 –auto-detect : Canon EOS 600D usb : 001,004 $ gphoto2 -L Erreur (-53 : « Impossible to communicate with périphérique USB impossible to use interface 0 : If there is no way to get gphoto2 to operate , would there be another means to operate my Canon EOS on Debian ? Thanks in advance for your help. Bernardhello, i'm not experiencing any errors using gphoto2 for my camera here and to make sure it hadn't changed recently i just snapped a picture and loaded it to my PC from my camera. i am using Debian testing. for what it is worth perhaps try a different cable and USB port and see if that helps. it may also be that the connection in the camera itself is going bad. when you plug it into the PC watch the system journal to see what it is reporting, perhaps something there has changed somehow. does your camera have any Bluetooth or Wifi options? these are things i think of, hope something helps. :) songbird
But then, ever since I de-installed and re-installed libgphoto2-6, my old scanner is no longer reckognized !! (EpsonScan V500). I tried to re-install the scanner with no success... I saw comments on the web about this old Epson scanner : users encounter problems with it on recent Debian distros... therefore most of them have now opted for "VueScan", which works well, but the licence costs $30 a year !
