no ACL set for hotplugged devices after upgrade to saucy

I see that udev in saucy has dropped udev-acl support, so this is probably related to that. Martin, you say in the changelog that logind is supposed to use uaccess now, but I don't see what/where that is on the system. Can you have a look here, please?

The rules are in /lib/udev/rules.d/70-uaccess.rules now, and in raring I backported current udev's "uaccess" helper to our old udev package (of course in saucy we should actually update to the current udev).

My webcam doesn't have a microphone, and I don't currently have an USB audio device at hand, so I cannot reproduce this and thus have to ask you for some further debugging. For a start, can you please attach the output of "udevadm info --export-db" with the device attached? Also, the output of "ls -lR /dev/snd" might be helpful.

Thanks!

udevadm db output attached as requested. Listing of /dev/snd included below. Note that the acls on controlC1 and pcmC1D0c have been set by hand - these devices had no acl set automatically.

$ ls -l /dev/snd/

I can reproduce this with a gphoto (PtP) camera and my scanner. This might be a botched uaccess backport in our udev (this was working in raring when I did it, but since then we got quite a number of changes.

This bug was fixed in the package udev - 175-0ubuntu28

---------------
udev (175-0ubuntu28) saucy; urgency=low

  * Build with --enable-udev_acl again, as this also controls the uaccess
    backport. Just don't install the ConsoleKit helper and the udev-acl rules.
