Logitech mouse over USB-c hub

[ryys]

Ok, finally bought a USB-C hub with some USB 3 ports, SD card slots etc. The problem appeared when I connected my Logitech MX Performance unifying receiver, my mouse either doesn't work at all or works VERY bad. I've already read a little how those receivers don't really like to work over docks/hubs but I can image tons of people using Logitech mouse with their usb-c only laptops. Is there any solution to this? Or maybe some hubs do better than others? I wanted to buy OWC or similar thunderbolt dock later on and plug this receiver into it as well...

BTW - it's the same situation, no matter if I plug PD power into the hub or not.

Unfortunately, there is no spectacular solution to this short of using a USB 2.0 hub. The interference is usually happening because the noise generated by the (USB 3) hub causes interference with the connection. Some hubs may be a bit better shielded than others and reduce it to some extent, but you are likely to find this issue on many of the hubs, and so many factors impact this that just because X hub works okay for someone else doesn't mean you won't have interference issues with it as well (so when you buy, make sure there is a decent return policy). In some cases, it won't necessarily result in no connection as well, but it will cause the cursor to be more jittery on the screen. You can try using Bluetooth if it is a Logitech with that capability (such as the MX Master 3), but the sound made by the hub can interfere with this signal as well. Alternatively, if you have a 4-port USB-C Mac, you can get a USB-A to C dongle and see if this reduces it and place this on the opposite side of the hub.

Possible solutions?

Solution #1:
Plug the unifying receiver directly into the Mac.

Solution #2 (never tried it myself, but I'm thinking it could work):
Get a USBc-to-USBa dongle like this one:

Cable Matters USB C to USB Adapter 6 Inches (USB to USB C Adapter, USB-C to USB 3.0 Adapter, USB C OTG) in Black

Cable Matters USB C to USB Adapter 6 Inches (USB to USB C Adapter, USB-C to USB 3.0 Adapter, USB C OTG) in Black

www.amazon.com

Plug the unifying receiver into the adapter, then plug the adapter into the hub.
The "extra length" provided by the adapter will move the unifying receiver "away from" the other hub connections, reducing the interference.

Thanks @ght56 and @Fishrrman ! Actually I've been using my unifying receiver through a very short usb-c - usb3 adapter and it work's fine but I don't want to waste one port (out of two...) for a mouse. In my remote configuration I need to plug plenty of stuff (1 port for SSD drive, 2 port for USB-C hub for PD, SD/microSD cards and the receiver). So there's no solution for wireless mouse, without wasting one port just for that, other than Magic Mouse? WTF Logitech?!
