Subject: 31-rc3-mmotm0716 - dead USB trackball mouse kills entire system
(Throwing at everybody in MAINTAINERS that might know something...)
OK. To start off - I *know* it's a trackball that is on its last legs.
However, (a) it's my favorite mouse design *ever* and (b) it's out of
production, so I'm trying to delay as long as possible replacing it.
Especially when the entire problem is that the USB cord has one broken/loose
conductor, which means that four or five times a day I have to wiggle the cord
a 1/16" to wake it back up, and I get this sort of spewage in my console logs
if running a -mmotm0702 or earlier kernel:

Pretty much what you'd *expect* to see if a device keeps dropping in and out...
Well... Usually. Today, on a -mmotm0716 kernel, the loose conductor struck
again, and no amount of wiggling would resurrect it as far as the system was
concerned. Note however that it *did* wake up just fine when I finally
rebooted the machine, even though I had not touched the mouse any further -
which says to me that the wires were making a connection again, but the kernel
wasn't picking up on it.
Meanwhile, in my kernel logs, I had:

The "can't reset device" is apparently new with mm-0716 - I've not seen it
before in at least the 6 weeks my logs go back. And it seems to be the
beginning of things going pear-shaped, even though it manages to reset the
device. A few seconds, the events thread whinges that not all is fine in USB
land:

And 2 minutes later, things are *still* not fine, and other things
are hanging as well. Since the 'events' thread is hung, both my mouse
and keyboard are dead (though alt-sysrq kept working, since it does its
magic behind 'events' back).
