Some users of the new MacBook Air and MacBook Pro This year they are having some problems. Errors appear when using an accessory connected to the USB 2.0 port. Apple has already been informed of this, and it will surely remedy it.
The first thing they will think of Cupertino is that it is the fault of the accessory in question, which does not meet the necessary specifications. But the funny thing is that the same accessory on the same MacBook works perfectly if it is connected to the port USB 3.0. We'll wait to see what Apple says.

Problems with some USB 2.0 accessories
Some USB hubs and accessories get disconnected for no reason.
Affected users report that they have connectivity issues with all types of devices that require a USB-A connection, including mice, keyboards and other accessories. Multiple hubs have been tested, suggesting that the problem is not caused by a particular brand of hub, and it also appears that most of the complaints are limited to USB 2.0 accessories rather than USB 3.0 and 3.1 accessories.
SMC resets, safe mode, Disk Utility repairs, different user logins, and OS reinstalls have failed to fix the error, suggesting that it may be something Apple needs to fix in a future macOS update, if it is a software problem.
