[BUG] Broken USB on StarFive VisionFive 2

[Heinrich Schuchardt]

Hello Hal, hello Minda,

USB on the StarFive VisionFive 2 is somehow broken.

The `usb start` via preboot results in an error.
When I stop and restart USB it works.

I am on origin/master (v2026.01-rc2-41-g69cc92d6869).

I have a single USB stick plugged in. I tried with different devices.

Best regards

Heinrich
