USB configuration has changed.

Environment

Resolution

This is an information-only event.

If the vCenter Server is flooded with this message and is causing performance deterioration, determine which host the message corresponds to and check the following:
- Any physical USBs plugged into the ESXi host server (reseat the USB)
- Any VM that has USB port integrated 
- KVM USBs
- If using USB passthrough, ensure compatibility
