This is what I ended up doing for now to eliminate the wired USB Keyboard and USB mouse... I replaced the wired mouse with a Bluetooth mouse. I would only need to use a mouse attached to the backup computer if the main computer was to fail, so I can put the mouse away somewhere when not in use. Interestingly, the shared mouse works on the backup computer BEFORE you’re logged in. Not so with the keyboard. I can’t log into the backup PC without an attached keyboard. I tried replacing the USB keyboard with the Windows 10 virtual keyboard, but the virtual keyboard doesn’t appear until you’re logged in... STUPID!!!... So I just eliminated the password, so the PC boots up to the splash screen, and then you can pop up the keyboard with the mouse. At this point though, the shared mouse and keyboard are fully functional, so there’s not much need for the virtual keyboard or Bluetooth mouse unless something goes horribly wrong on the host computer. If absolutely necessary, like with a complete failure of the host, I can easily just move the transceiver for the Gearhead wireless keyboard and mouse to the USB port of the backup NUC PC.My laptop has BT, so it's quick, but it won't wake the laptop if sleeping. The M585 is supposed to be able to use 2 unifying receivers as well .. Haven't tried it.
