I have a problem on the brand new Mac (2 different ones, after getting a replacement) where USB A devices stop working every few hours and don't work until a reboot. I've tried 4 different USB hubs including Apple's own USB-C to USB-A connector. I've tried different computers, keyboards, mice. Nothing works. After about a month of back and forth with Apple, they finally admitted it was an operating system bug.

I can't debug it or even view USB requests because Apple has now locked everything down. The internal display sometimes doesn't work until I restart.

USB devices on the brand new MacBook Pro 13" do not work for more than a few hours. Apple does not care about macOS.

Here's a thread of other people with the same issue: https://www.reddit.com/r/mac/comments/gp5b1z/usb_20_issues_o...
