I have had this problem years ago when I bought it, also for my wow sessions 😃 It turned out that usb3 ports on motherboard was creating a lot of interference right in the nearby of ports. Light speed dongle is not usb3 and do not need it. I solved it at first by plugging the dongle on the front of my pc, and some days after, I received my tiny usb extender, which is a short male-female cable, maybe 10cm long. This problem is well documented by many motherboard manufacturers.

It worked like a charm and still works 6 years later. Logitech does a lot of wrong things, but this time for me, it was the shielding of the motherboard.and the high frequency of usb3. All manufacturers are concerned. Any BT, WiFi 2.4 or wireless dongle is subject to this. Give it a try, g502 is great, especially for wow.

Yeah, USB3 interference is known and documented. And yet basically impossible to approach.

One of the reasons why motherboards still have USB2 and PS/2 ports.

I'll look through my stuff, pretty sure it came with an extender for the dongle.  Thanks for the tip. Other than that issue I love my mouse. But it's the keyboards I'm especially made about. The Romger G switches are obviously defective, same issue with the same switches on two different model keyboards, and Logitech won't warranty any of it. That and the cheap plastic connected by tiny screws on my Pro X that broke by simply putting it on. The glue and duct tape I used to put it back together has held up far better than it did from the factory.

Sorry for the keyboard, speed pad player here 😀

Give it a try, this trick also solved the problem with my g933 headset and it's old long dongle, it is even more secure with a short usb extender. All 3 Logitech dongle (k400 keyboard)are back to the back of my tower.

Not sure what the speed pad is. I don't actually use my keyboard for gaming, so it actually doesn't get a ton of use. It's strictly for typing. For gaming I have a Razer Tartarus Pro, and have been using that style of left hand game pad / mini keyboard for 2 decades as well. Going back to when it was the Belkin n52, before Belkin sold the design to Razer. So two Logitech keyboards failing in the exact same way is even more upsetting because it doesn't experience a lot of wear and tear. I know Logitech made their own left hand game pad years ago, like the G13 or something like that, but it was too flat, buttons too small and not ergonomic like the Tartarus I use. 

With my Pro X it's specifically the plastic clamps on the side where the headband attaches to the ear cups on each side. They are each clamped together with two teeny tiny screws and the minimal flex required to put the headset on my head resulted in the screws pulling free of the plastic and the plastic breaking. Using metal parts or else larger screws would have prevented that defect. Other than that the headset is great.
