W10 pro x64)
I just did a test (I know, 'WE don't do tests' )
I have a Aluratec USB VGA (trigger t1) adapter. I added a 3rd Monitor via that. Monitor 3 works. But then the K4 fails (was working in Calibre before)
I disconnected the Monitor and looked at the Device Manager
<attached device properties>
Bad descriptor?
This may extend this issue to ALL USB Video users
