So I start to view Apple logo > About this Mac > System Report before, during and after this happens, refreshing the view constantly. This is weird and suggests it's the Mac and not the hubs or devices. that earlier discovery that USB 2.0 devices freeze even across different simultaneously connected USB-C hubs. I run this and to my surprise the issue occurs whilst it is running.
the USB 2.0 devices still freeze across all hubs at the same time If I put the mouse in any USB-C hub, and put the keyboard in any other USB-C hub and connect these to any Thunderbolt USB-C ports.Both of the above with all of the USB-C hubs I have (still freezes).Razer DeathAdder by itself (still freezes).Filco Majestouch keyboard by itself (still freezes).
Maybe it's one of the USB-A USB 2.0 devices? So I have used: Unplugging and inserting the USB-C hub does not solve it. Using any of those hubs, with the 2 USB 2.0 devices attached, at some point the devices will freeze up.
Feel free to cite this when contacting Apple if you are experiencing this exact issue. This is logged with Apple as support case 101088030092. after a while (minute or hours) the USB 2.0 devices will stop responding (keyboard dead, mouse not moving or clicking). When I use an external USB-C hub in any port of my MBP ( MacBook Pro 2020 13", i7, 32GB RAM, Four ThunderBolt 3 ports ), and connect USB 2.0 devices that include a Filco keyboard and a Razer DeathAdder mouse. The issue appeared on day one, I contacted Apple on day three. I work in tech and have been an engineer for years so I'm not new to figuring out issues, I like to get to the root cause.
This is my first Apple device so I've had to learn how to use it whilst debugging it. Apologies for posting with a new account, but I would like to share an issue I've encountered that I think is widespread but I've not had a great experience with Apple acknowledging that the issue exists.
