Joseph Salisbury the tablet is already working correctly now. The only
problem was that since I upgraded from Ubuntu 15.10 the digimend-dkms
package (which is not in the xenial repositores - seems to have been
integrated in the kernel) remained. Once I removed this package and
rebooted, the correct modules were loaded and the tablet worked as it
should. It is not a driver issue, it is a packaging issue, the package
needs a "Conflicts: digimend-dkms"

Title:
  huion tablet is not recognized anymore in Ubuntu 16.04

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Gaomon 860T tablet was being used normally and also recognized
  automatically in Ubuntu 15.10. However, when I did the upgrade to
  16.04 it just stopped being recognized. The USB devices show in dmesg
  and the tablet also works normally in the dual-boot windows, also the
  modules seem to be loaded, the digimend-dkms package is installed, but
  the device(s) simply do not show up at all, as if the tablet was not
  plugged in.

  dmesg| grep huion shows this:
  [  152.462541] usb 2-1.2.1: Manufacturer: HUION

  however, nowhere the devices are being created:

  Compare with the display of xinput list when the tablet worked (in a
  different machine):

  Again, libwacom-list-local-devices does not show up, only the bogus device:
