Just received my UHK80 with key cluster and trackball plugins.
The trackball works perfect on the trackball plugin.
However the mini trackball on the key cluster is super intermittent and I can’t scroll properly.
Given I just received this keyboard a day ago, should I consider this as a faulty part?
I tried this on both Bluetooth and Cable.
I already raised a support ticket.
Another question, should I expect to find any USB dongle in my package? I couldn’t find any.
