Hi, Since all Windows USB traffic is ultimately routed through Parallels, it should be possible to dump all traffic or traffic of a single device into a file. Might it somehow be possible to actually do this in Parallels in some future version? I know this feature request is only useful for developers, and a very specific group of developers at that, but it sure would help me a lot Apart from that, I suppose you already have this feature implemented in your own in-house versions of Parallels. Kind regards, Khamba
