I *could* plug the mouse in, using a USB A to USB C converter (I have one like what you linked), and would give that a try before plugging in a wireless dongle. I used to use Windows for this, but since Windows Movie Maker is no longer available, I switched to iMovie. I use the card reader to transfer video files from my camera to the Mac (now) for editing and then unplug it. Since the MacBook Pro only has 4 USB/Thunderbolt ports, I would really rather not have a dongle hanging off of one all the time, seems counterintutive to having a portable device LOL. I purchased it from Amazon specifically to use on both my Mac and my desktop (specifically got a USB C device).

It would be strange for a card reader to cause electrical interference, and I have used this card reader on my Windows 10 device numerous times with no ill effects.
