Yes, I think this should stay open. I haven't heard anything since I replied to 
Ben Gamari on 14 February. having said that, I haven't experienced the lock up 
again since I reported it. Perhaps it's been fixed without me knowing.

So, do I understand correctly that you're unable to reproduce the problem?

I figured out a work around for this.  Once the bluetooth adaptor has been detected and udev
had done its stuff run: 

hciconfig -a

With this user space change it works.  I have no idea why the 'hciconfig -a' query fixes things.
I run gentoo and bluez-4.87 is installed.

OK, thanks for the update.  Do I understand correctly that things used to work
before without that workaround?

From the original report:

I just noticed this: the device is claimed by OHCI, then ~150 seconds later(!)
it disconnects and then gets claimed by EHCI, presumably while it's in use.

Probably what happened is that Ed unplugged the device after 150
seconds of non-operation, and then four seconds later plugged it into
an external high-speed hub.

Yes.  The problem is understood.  It can be bypassed by doing a 'hciconfig -a', which
puts the device in a state where it works.  As far as I know its not fixed yet.

Bugzilla seems to be down.  This is solved in 38.4.
