Sometimes USB does not work.

[Rob van den Berg]

Sometimes after booting, USB does not work
I can't use the keyboard or mouse to find out. Only solution is to kill the system by long-pressing the powerbutton.
The second time I boot, the USB system works.

Rob van den Berg, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (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-3.16-rc7

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.

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

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.

problem is that sometimes it works and sometimes it doesn't ... so installing a new kernel and usb works fine that isn't a solution is it.
But today usb stopped working and I found this in kern.log

Sep 12 11:52:55 lesruimte kernel: [ 22.266768] xhci_hcd 0000:00:14.0: HC died; cleaning up

attached is the kern.log

Rob van den Berg, the latest mainline kernel available for testing is now http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17-rc4-utopic/ .

I have had this problem on the same hardware (Dell Inspiron 3847).
Upgrading the kernel to 3.16.2 (using the "mainline" packages) seems to have solved it.

[Rob van den Berg (rghvdberg)]

thanks for your suggestions @penalvch and @setaou

running 3.17.0-031700rc5-lowlatency for a couple of days and I haven't noticed any usb failure at startup

should we mark this bug as closed / fixed ??

[penalvch (penalvch)]

Rob van den Berg, as the mainline kernel is not supported in Ubuntu as per https://wiki.ubuntu.com/Kernel/MainlineBuilds#Does_the_kernel_team_support_the_mainline_kernel_builds.3F , the next step is up to you. If you would like to see a fix backported to a Ubuntu kernel, one would need to reverse bisect the kernel in order to identify the fix commit following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F .
