A small edit to the eeinfo. Since udev 104 you need to be in the "usb" group as well. pkg_postinst() { elog "Don't forget to add yourself to the plugdev and usb groups " elog "if you want to be able to access your camera." } Reproducible: Always Steps to Reproduce:
Strange? For me it is enough to be in plugdev. Just an Idea: "plugdev" can be replaced with a group with a more speaking name? Scanner also get group "scanner".
Recently I found when UDEV updated from 103 to 104 my camera stopped working. We found that: ATTR{idVendor}=="04a9", ATTR{idProduct}=="3126", MODE="0660", GROUP="plugdev" causes the camera not to work when the user is in the plugdev group It also causes # find /dev/bus/usb -ls to show up in the USB group: 399542 0 crw-rw-r-- 1 root usb Feb 13 00:16 /dev/bus/usb/001/030 -------- Now what's supposed to happen and is the camera is in the plugdev group. When editing ATTRS{idVendor}=="04a9", ATTRS{idProduct}=="3126", MODE="0660", GROUP="plugdev" (note the S) It fixed the group issue showing the camera in the Plugdev group.

Correction: Was not UDEV 103-104 it was actually the last revison of media-libs/libgphoto2-2.3.1-r3
Fixed in libgphoto2-2.3.1-r4.
