Also annoying that the unifying receiver doesn't work with a Thunderbolt dock. I tried using it for a while and got a lot of lag and stuttering. It was really bad. So now I have a Thunderbolt dock that everything else uses, and a single USB-C to USB-A adapter hanging off the laptop just for the precious unifying receiver. I'd be less annoyed if it was USB-C plugged in directly, but still not happy.

Previously I used a wired mouse, plugged into the dock, which worked great. However, I needed a new mouse as that one started to fail and the only options available through my company were wireless.

Try connecting it to a USB2 port, use a USB extender, or a USB2.0 hub. This is a know issue with USB3 ports: https://www.usb.org/sites/default/files/327216.pdf

Fascinating. I'll have to see if I have an old USB extender lying around in my big box of old cables. Thanks.

my favorite thing about this doc is that all the pictures are clearly drawn in ms paint.

This is the most infuriating thing about my MX Master 3 mouse. I mean, it’s fine now. But for months I’d have mouse stuttering/completely unresponsive and have no idea why.

I’ve found that if I use it on an extension lead on a USB 2.0 port (i.e. via another hub) it works fine thru a TB dock

This is a well enough known problem that a company I used to work for had warning labels on their TB docks telling you how to avoid this.

Which dock do you use? I also have the same issue but it was the dock's issue in my case.

That's the dock I have. Someone else posted a link to a white paper from Intel that mentions this is a USB 3 issue, not one specific to the dock, but it is good to see Caldigit offers the same solution on their site that is mentioned by Intel. That gives me a reasonable amount of confidence that it will work.

Was it the fact that it was connected to your dock that caused the lagging and stuttering issue or was it the location of the receiver when it is plugged into the dock?

The reason I ask is I have noticed this issue too when too many things are placed between the receiver and the device.

From the other comments here it sounds like an issue with USB 3 that can be resolved with a USB extension cable.

I didn't have anything other than the laptop between the receiver and the mouse. I was going to try and move it closer to see if it helped, but with some of the other cables plugged into it, I can't really move it much.

Yeah, I have had the same issue with my jabra headset for years on a cal digit TS3. It goes away if I plug it into a separate USB port on the MacBook. My guess as to the problem is the bandwidth allocation and prioritization on the thunderbolt.

But that’s a wild ass guess.

Check out some of the other comment in the thread here. It sounds like it's an issue with USB 3 and can be resolved with a USB extension cable to move the receiver away from the rest of the ports.
