#65 Roccat Ryos MK via uniclass kvm switch on Ubuntu

[Full Name]

My Ryos MK won't work on Ubuntu (14.04-16.04) when plugged into my KVM switch. However, the keyboard works fine when I boot Windows or go into BIOS, so the KVM switch itself works with the keyboard.
This is the output of dmesg:

What could be the problem here?

Is there anything I can do or test that would help finding the problem?
