I got my new Wyze watch this morning and plugged it into my computer to charge it up. I rebooted the computer while it was charging and when the computer came back up, my mouse pointer was gone. Mr. Mouse was no longer in Device Manager and even plugging in an old standby wired mouse did nothing. Several reboots and other attempts were of no help. The watch was then charged so I disconnected it from the computer and on the next reboot, the mouse was back. Maybe it was a coincidence or maybe the watch and mouse driver interacted in a weird way. I don’t know, but if anyone finds their mouse pointer disappearing while they’re charging their watch, the watch could be the culprit. Just a heads up in case it happens to anyone else.
Have you tried with any other charger cables? The watch cable only charges the watch so o don’t think the watch would send or have any type of data/commands to have the computer see it as a mouse.
