I mostly cleaned, etc. its usbmon support (which was originally added by Christoph Zimmermann). Anyway, you're always free to try to add support for another file format. I must say that Micah was rather easy to work with. > Btw, it seems that most of your work is focused on getting VMware logs. Micah had a vmware.com address last time I contacted him.

This is not something I know much about. I tried to use some digital camera over USB with qemu without much success. Apparently qemu's USB pass through has little chance of supporting high bandwidth USB devices. See http://lists.nongnu.org/archive/html/qemu-devel/2010-09/msg00017.html for the - not very interesting - answer I got when I wanted to know more about the problems of USB pass through in qemu.
