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.

(this lack of options is probably unlike what other Board/BIOS do offer.) excerpt from kern.log: Sep 19 22:35:23 dtaa-flc21 kernel: [ 57.575918] usb 2-5: USB disconnect, device number 3 Sep 19 22:35:27 dtaa-flc21 kernel: [ 62.009193] usb 10-2: Device not responding to setup address.
