Episode 1818

Darryl from Loveland, CO

Darryl is a developer, and he has many devices that rely on USB in Windows. But when he tries using them on Surface Pro and Windows 11,  they've stopped working due to the latest Windows update. Leo says it could be an out-of-date driver, but remember that Windows 11 is in Beta and it's likely just a bug. Report it to Microsoft through their bug reporting tool. What he could try is to reboot in safe mode, then remove the drivers manually. Then remove all the files, and reboot. Then reinstall the new drivers. He should be fine then.
