Hello,

I'm trying to debug an issue with udev not registering my camera properly on Slackware 13.37. When I run udevadm monitor --property, it shows this when I plug in and then unplug the camera:

The fourth entry is the one that is the most descriptive and is the one I want (I'm trying to get my camera working with Shotwell--a photo manager). However, Shotwell's call to gudev never returns this device, and I'm starting to suspect it's a problem with the way udev is set up. When I unplug the camera, that same device (that has ID_VENDOR, ID_GPHOTO2 and GPHOTO2_DRIVER) is not listed. However, there are 6 devices added and 6 removed, yet none of the ones removed have ID_VENDOR set, etc. On Ubuntu, unplugging the camera, shows the same device when it's removed, so I'm guessing it's something Slackware is doing with udev. It's almost like it's clearing out ID_VENDOR and so right after it's added..? This is way out of my comfort zone, so forgive me if some of what I say doesn't make sense... but any ideas what could be causing this?

Thank you,
Brad

I now think it's a problem with gvfs-gphoto2-volume-monitor not taking control of the device, so nevermind. :) GVFS doesn't come standard with Slackware, so something's not configured properly.
