Public bug reported:
I'm trying to reverse engineer USB communication. Device 005 on Bus 001,
a SONY camera. It freezes on this specific motherboard (nVidia chipset).
It does not freeze on an Intel/Atom motherboard of a second computer. I
suspect it has to do with chipset support but I lack the skill,
experience and time to look into this.
