It is my understanding there is an outstanding bug in the usb code 
handling device enumeration for umass devices (and some others).  This 
manifests itself by the symptoms you see.  I believe the explorer thread 
is blocked so device detection stops.  I have personally seen this bug.

Unfortunately the person that was going to fix this has been away for 
awhile and will not return for another month so unless someone else 
fixes it 8.0 will ship with the bug.
