>Description:
When I boot up from the NetBSD HEAD image, it fails to enumerate USB devices and I get this error:

I did an OCR from a camera image, and tried my best to fix the text. So, some text might be a little off. 

>How-To-Repeat:
Boot up from HEAD - 10.99.4. It happens every time.
>Fix:
None
