I have a USB hub that's built into my Viewsonic PT775 monitor. The hub

When the hub is disconnected, whether by unplugging it or turning
off the monitor, I get a panic in 4.7p3 if there are no devices
connected to the hub's downstream ports.

I'm not sure? I didn't have anything running, that I could tell, that
would have had the uhub device open. The machine was sitting idle at the
login prompt. If someone would like to point me at a list of what I need
to do to produce useful debugging information, I'll gladly do so.
There are a number of brokenisms in the USB stack in -stable. As to
whether they will get fixed or not is a matter of whether anyone has the
time to MFC the USB stack from -current or not. It's much better over
there, and I've already merged the framework to make it easier to MFC,
but it is very unlikely that I will be attempting the work myself as I
don't use USB on -stable myself.
So the problem I'm having is a known issue when detaching a uhub device, then?
