>Description:
With the usb2 stack, devices which are used via ugen don't report being disconnected. For example after connecting and disconnecting several times:

ugen2.2: <Motorola Inc.> at usbus2
ugen2.2: <OpenMoko, Inc> at usbus2
[last line repeated 11 times]
ugen2.2: <Linux 2.6.24/s3c2410_udc> at usbus2
ugen2.2: <OpenMoko, Inc> at usbus2

It would be nice if the disconnection could be reported too, especially since some devices go into power-saving mode automatically and disappear from the system without user intervention.
>How-To-Repeat:
With only the usb2_controller_* modules loaded, connect and disconnect a USB device.
