[Bug 1033727] Re: USB passthrough doesn't work anymore with qemu-kvm 1.1.1

[Michael Tokarev]

Peter, are you able to run git bisect or something like that, to try to
pinpoint either the commit which introduced this issue or which fixed
it?

I tried to reproduce this issue several times with various devices, but
I can't do it reliable, it always more or less works on my machine.  If
I were able to, I'd bisect it long time ago.

Now, to clarify things, I've no idea how USB works internally and how it
is implemented in qemu, for this issue I can only do a bisection to find
the changes which change the issue.

You can ping me by email or hit me on IRC (I'm mjt at freenode.net and
oftc.net) if you're willing to debug it further and need help in doing
that.

Besides, what are the sympthoms of the device non-working?  Does it
happen with linux guest too?  Have you tried re-running the guest again
when the problem occur, using the same problematic version of qemu - I
mean, is it 100% reproducible or happens at random?

Thank you!
