USB issues after update

After updating my M1 Max Mac Studio to Ventura 13.4.1 none of my USB drives, external SSDs, USB keyboards, Midi Controllers work. Is there a fix for this bug?

Check the "Security & Privacy" System Settings to see the setting for "Allow Accessories to Connect". Maybe toggle this setting to another value such as "Automatically when unlocked" to see if those devices now work. Maybe something with this setting became corrupt especially if you had it set "Ask for New Accessories" as the update may have corrupted the acknowledgement of previously allowing previous devices. I gave up and just selected "Automatically when unlocked" on my Mac since I lock my Mac when I'm away from it.
