From Handbook chapter 11 "Finalizing your Gentoo Installation": "The groups the user is member of define what activities the user can perform. The following table lists a number of important groups you might wish to use: ... usb be able to access USB devices" As i see for udev this behavior was set by this ticket: https://bugs.gentoo.org/show_bug.cgi?id=150223 But for now /dev/bus/usb is owned by root:root. There is no rules to correct ownership in udev shipped with sys-apps/systemd-207-r2. And i think this is true for sys-fs/udev. With sys-apps/systemd-207-r2: ls -l /dev/bus/usb total 0 drwxr-xr-x 2 root root 120 Oct 15 20:24 001 drwxr-xr-x 2 root root 120 Oct 15 20:28 002 drwxr-xr-x 2 root root 60 Oct 15 20:24 003 drwxr-xr-x 2

This got dropped upstream in udev-158. http://git.kernel.org/cgit/linux/hotplug/udev.git/commit/?id=bc6788184011fc05bfd3c59f0252d90ac0263c33 http://git.kernel.org/cgit/linux/hotplug/udev.git/commit/?id=b93e0709497e37a5fb023b8b3c5c47a425123193 It looks like we maintained it in FILESDIR for a while after that; hard to tell when it got dropped in CVS.
I think this got dropped from Gentoo between udev-164 and udev-167.
The reason why i opened this ticket is that games-util/xboxdrv can not be run by non-root user even if user is member of usb group (as per Handbook). It uses libusb to access usb devices.
We still install 40-gentoo.rules from sys-fs/udev, like so: $ grep usb *.ebuild udev-204.ebuild: # Gentoo specific usb group udev-204.ebuild: SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", GROUP="usb" udev-208.ebuild: # Gentoo specific usb group udev-208.ebuild: SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", GROUP="usb" udev-9999.ebuild: # Gentoo specific usb group udev-9999.ebuild: SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", GROUP="usb" $ ls -ld /dev/bus/usb/00?/00? crw-rw-r-- 1 root usb 189, 0 Oct 17 23:02 /dev/bus/usb/001/001 crw-rw-r--+ 1 root usb 189, 1 Oct 17 23:02 /dev/bus/usb/001/002 crw-rw-r-- 1 root usb 189, 2 Oct 17 23:02 /dev/bus/usb/001/003 crw-rw-r-- 1 root usb 189, 4 Oct 17 20:02 /dev/bus/usb/001/005 crw-rw-r-- 1 root usb 189, 128 Oct 17 23:02 /dev/bus/usb/002/001 crw-rw-r--+ 1 root usb 189, 129 Oct 17 23:02 /dev/bus/usb/002/002 crw-rw-r-- 1 root usb 189, 130 Oct 17 23:02 /dev/bus/usb/002/003 crw-rw-r-- 1 root usb 189, 256 Oct 17 23:02 /dev/bus/usb/003/001 crw-rw-r-- 1 root usb 189, 384 Oct 17 23:02 /dev/bus/usb/004/001 Looks like sys-apps/systemd specific problem.
Ah, I didn't even think to look for a heredoc in src_prepare. So, my thoughts on possible resolutions: 1. Do nothing; if users need this they can install a rules file in /etc/udev/rules.d. 2. Install 40-gentoo.rules as part of gentoo-systemd-integration. 3. Push for a shared package to install 40-gentoo.rules. This may be overkill for a 4-line text file which includes one rule that we don't even need. I'm leaning towards #2 at the moment.
