A CHERRY DW 3000 Cordless Desktop (Mouse and Keyboad combo with an USB receiver) is not recognized by USB Server on a Nvidia shield TV box. On the Nvidia shield TV itself the combo can be used. Any idea why it’s not recognized by USB server? (The USB server is licensed. No ignored devices. Other devices are working (Logitech K400+ and K830 (both wireless keyboards with touchpad), Logitech MX Anywhere 2s mouse, Samsung SE-506AB Blu-Ray writer).
