Bug Description

Here, I am trying to connect my ipad 2 running iOS 7.0.4 to a laptop running Ubuntu 12.04 via usb. After connecting the two devices via USB, Ubuntu displays the following message in a popup:
    The device 'Stephens iPad' is locked. Enter the passcode on the device and click 'Try again'.
A second later on the ipad a modal popup appears saying something like the following in English:
    Trust this computer?
    Trust / Don't trust

After clicking 'Trust', a popup appears on Ubuntu:
    Unable to mount Stephens iPad
    DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)

On the ipad, the modal popup reappears. Clicking 'Trust' again gives the same result as before. Via dmesg, the following entries can be seen:
    [ 282.768166] usb 1-1.2: new high-speed USB device number 4 using ehci_hcd
    [ 289.694066] usb 1-1.2: USB disconnect, device number 4

Stephen Kun, thank you for reporting this and helping make Ubuntu better. Could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, please just make a comment to this.

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc6

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

the Ubuntu version taken from http://cdimage.ubuntu.com/daily-live/current/ on
2nd Jan, 2014. This time the error popup on Ubuntu states:

Hi Christopher,

I've verified that the problem still exists in the latest
daily-live/current version.

I still have that version on a USB stick 'A'. In order to test the upstream
kernel, can I do the following:
o Download the kernel image DEB package onto USB stick 'B'
o Boot from stick 'A'
o Install the new kernel from stick 'B'
o Reboot from stick 'A'
o Test connection to iPad

I don't want to get my standard installation messed up (Win7 / Ubuntu12.04
dual boot). I don't understand enough about where the kernel gets installed
and which MBR gets updated.

Can you advise me please?

Thanks
Stephen Kun

Stephen Kun, thank you for your comments. As a considerable amount of time would be spent attempting to slipstream the mainline kernel in the live environment, it would be best to just install the mainline kernel as previously requested, and you could always boot back into your prior kernel and delete the new kernel via the instructions previously provided.

Do you mean I should install the mainline kernel into my 12.04
installation, then do the test?

I didn't realise that an old 12.04 would work with a really new kernel. If
that's what you meant, then let me know and I will give it a try.

Regards
Stephen

With latest upstream kernel, linux-image-3.13.0-031300rc7, the system fails to load init, so I'm unable to tell if this bug applies.

Sorry, my mistake - chose the x386 kernel to match my Intel processor. Actually needed the amd64 kernel.
With the correct kernel, I was able to verify that the bug exists in the latest upstream kernel.
