I've installed a UTech MMO Gaming Mouse, and for a while it was at least able to send keystrokes from the side keyboard, plus the lights were on. Now, although left/right click work, the lights are off, the side keyboard no longer works, and the UTech software no longer works.
The USB icon in the lower right of the VM window does show the mouse is present.
What did I do, and how do I reverse it? VirtualBox, guest additions, and Windows are current as of 12/31/2020
Thanks
