Nice to heard that it works with VMware. I might just add the USB IO logging feature to VMware so people don't have to sniffer VMware again.
You need to have more information on what is happening in the IO. I think you are not interested in the IO that upload the firmware. You might want to consider the USB snoopy pro which can be down load from sf.net. It is a tool that runs inside windows.
