USB-devices connected to dockin not recognized when connected at boot

[Andreas Noteng]

My laptop is mostly connected to a docking station in my office. If the computer is docked when booting, the USB devices (keyboard, mouse) are not detected. If I remove the computer from docking and then reinsert everything works as expected. Monitors and network connected to the dock does not have this issue.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.8 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I'm sorry for the late response. This problem only happens when I use my docking at work, but I usually only have time for playing around at home, where there's no docking.
Unfortunately the bug also exists in the mainline kernel.

[Andreas Noteng (andreas-noteng)]

The problem seems to have gone away. I don't know when it was fixed for me, has there been a recent kernel update?
After reporting this bug I reinstalled using kubuntu installer, but later switched to mate desktop. I do know the problem was still present after installing kubuntu, but it has gone away some time after that.
