KVM 0.15.0 crashes with USB

[giner]

pve-qemu-kvm_0.15.0-2_amd64.deb crashes at the same time as I attach usb device to it
pve-qemu-kvm_0.15.0-1_amd64.deb (previous version) mostly works well but I've got one problem (hopefully I found work aroud)

Let's go deeper about 0.15.0-1 version problem.

We have:
- Windows XP in KVM
- Prolific PL-2303 USB to Serial adapter

Problem:
I've installed Prolific usb to serial driver into Windows XP and tried to connect to the device and as soon as I press "connect" KVM crashes (no blue screens, KVM process just disappears).

Work around:
Prolific driver sets COM4 as a default. I've changed it to COM2 and ... it works! It's kind of magic, I don't know why. I've tried that experiment several times and result was the same:
COM4 - KVM crashes
COM2 - KVM works without any problems

I'm not sure how to debug it and who can I ask to help with fixing the problem but at least this information could help someone to get it works.

Regards,
Stanislav
