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 v4.14 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.

After a reboot a HD is recognised perfectly as well as USB storage sticks or the uPython board. After a few swaps the system seems to get confused with what got connected. Mount times increase (with the HD mounting fastest) and the uPython board the slowest. In the syslog after a fresh boot the devices seem to be recognized as sdx devices but after the swaps the syslog reveals more attempts to add xhci devices. In these cases the syslog gets flushed by messages of the same type: Sep 28 16:20:57 mbpr13b kernel: [ 4415.337728] usb 2-1: Disable of device-initia ted U1 failed.
