usb issue Macbook Pro VM Fusion

Hello,

I run a fbsd current in a vm instance on my MacBook Pro.

Today I did the upgrade to todays sources.

Now I get some annoying warnings from the usb stack:

The last lines above are repeating on the console.

There is no 'known' usb device attached to the port. Means, I have 
nothing attached to the usb ports externally.

If you need the full log, let me know.

What else can I provide to help debugging?

TIA,
Andreas
