- Specifically, the problem seems to be related to the use of hubs or adapters.
Apple's 2020 MacBook lineup seems to be having issues with USB 2.0 when used with adapters or hubs.
As reported by MacRumors:
One MacRumors reader noted that the USB devices connected to a Mac through a hub would just lose connection and stop working at random times, using two different USB-C hubs. Peripherals include external monitors and USB audio interfaces, as well as a mouse. With each instance, the monitor would continue to work, but the USB devices would fail.
As the report notes, many similar complaints note that USB 2.0 accessories seem to cause a multitude of freezing and disconnection issues, but that there's "no clear pattern" as to which devices are affected, or what might be causing the issue.
All of the usual avenues have not been successful in addressing the bug, and as the report notes Apple may need to patch this in an upcoming iteration of macOS. One possible workaround involves using USB hubs with terminating proxies, rather than transparent proxies, one Reddit user noting:
