comment Getting my USB headset to work with ChrUbuntu kernel
From the udev output we can see that a device is added to your system to communicate with it as a generic USB device, but that's no help. It isn't being recognized as a sound device. What is the product called? How is it described on the box? Is it a new version of a similar (Logitech?) product? How long has it been on the market?

comment how to make disk partition in ubuntu after installing ubuntu?
When you set up your disk partion when you installed Ubuntu did you leave any space or does your one partition take up the whole drive?

comment GIMP fails to load
PPA's aren't really part of Ubuntu. You should probably pursue the issue with the owner of the PPA. They may know of the problem. It may simply not be compatible with 12.04.

Where were gimp 2.8 and libgegl-0.2 installed from? I see earlier versions in Precise myself.

comment Why can root still edit files with a permission of 0?
@RichardNixon, excellent addition about chattr +i. I tested that and got it to work. No need to add your by-line to the text of your changes. It just makes the answer longer. The AskUbuntu site will keep track of what Lucio said and any edits anyone else makes. Click on the time of the last edit to see the history of edits. Thanks to you both.

Anyone can either edit anyone's question or answer, or at least suggest an edit by clicking on edit--no need to make it a community wiki item. I'm not sure you understand the UID stuff, though. It's easy to change the owner (represented by the owner's UID) of a file with chown, but one shouldn't change the UID associated with a username. One shouldn't generally change the passwd file directly, instead use commands or the gui to add users and groups and adjust permissions. That way everything matches up.

comment Why can root still edit files with a permission of 0?
Excellent. I'm glad Lucio's answer was of help. I should note that more UID doesn't usually mean less capabilities--it's not that simple. It is just that UID 0, root is special. The match between file permissions and the owner and group a file belongs to, and any other access controls, determine access. File ownership can be changed with chown, and group ownership by chgrp. Generally the more groups a user belongs to the wider access they will have. Here's a reference: askubuntu.com/questions/83/how-do-file-permissions-work

comment What security policies exist in place for packages and scripts?
The repository stuff is debian/Ubuntu etc. related. There's also the issue of binary only software in the Ubuntu Software Center that is specific to Ubuntu.

Clarify a couple of things; mention public key cryptography when gpg is first mentioned

The next step may be to search /var/log/udev for the matching device. Please look for and copy to your question any block of information from that file containing v046D (capital D). We know the device is on the bus from lsusb. The udevd daemon should have discovered it and created a linux device for it.

comment Showing “boot:” trying to install ubuntu from usb stick created with pendrive
I think that this message may be from syslinux, which is boot loading software for non-hard disks. Is there a SYSLINUX banner on the screen and then an error message before the line giving you the boot: prompt? If so, what's the error message?
