Hi,

The problem is that my cameras are no longer seen as USB devices when I connect the USB cable to the PC and turn the camera on. I run a Slackware distro.

Gphoto2 is something that has worked for years for me. but I no longer can figure out how to make it work on a newer 3.18 kernel. I have been using a card reader instead of gphoto2 for some time, but I wished to start using gphoto2 again. But what a surprise! I can no longer make it work.

All USB devices work perfectly, but if I connect a camera either a Canon A620 or Fuji XE1, lsusb shows nothing, dmesg has no entry, /var/log/messages is also silent.

I installed libgphoto2-2.5.7 from source (as I usually do). But the problem seems to be related to the kernel or some kernel parameter I should set. I am looking for something that has changed recently. For example /proc/bus/usb has disappeared. It seems that the mount point was needed at some point by gphoto2 but I am not sure.

I would be grateful for any clue.

When you plug it in run
to see what the system thinks it is.

If it is a /dev/?, try mounting it manually.

I didn't see anything. However it turns out the problem was a faulty USB connector. Sorry about that. With a good connector I now see the expected entries in dmesg.

Thanks.
