Pen doesn't work without cable
I have an Inspiroy 1060Plus Huion graphic tablet,
i've trying to use it with my Pen80 (that is the pen for this tablet) but i can't use it witouth plug in the cable.
When i plug the light is red, and works, if i take out the cable, the Pen80 doesn't work. I've bought another NEW pen80 and still the same problem.
I have a Dell Xps15 from 2012, Windows 7, 64-bit.
I've tried to re-install drivers, i've tried to remove 'windows ink', i've tried everything, but i cannot get that it works.
Can you help me please?
