FIXED: Windows 10 Logitech MK850/M720 Triathlon Mouse Freeze/Unresponsive

I have just bought a new Logitech MK850 keyboard and mouse combo – primarily for the multiple device support – and so far so good (The keyboard is a little mushy though – especially the backspace key, but hoping I’ll get used to it).

However – one problem I did find was that when sometimes, when my PC was either heavily loaded or reading a lot of data from internal disk, the mouse would and keyboard would freeze and become unresponsive.

I’m using the Unifying receiver in this case, and have it plugged into a USB 3.0 Hub port on the front of my PC. Searching online appeared showed a thread where someone had a similar issue, and suggested making sure it’s plugged in to a USB 2.0 not USB 3.0 port on the PC. I’ve just moved the port, at this appears to fix it!

TLDR; Plug into a USB 2.0 port, not a USB 3.0 port!

UPDATE 03/09/2020
My freezing and unresponsive issues seem to have returned, but I don’t know what I’ve changed. I’ve now tried moving the unifying dongle from the USB port in the front hub to the rear instead, but that doesn’t appear to have fixed the issue.
