Mark,
If I remember correctly - u had mentioned that you had started
working on USB virtualization. How much progress have you made?
I would be interested in contributing/learning to/from the USB
virtualization project.
If you have time pls give me some detailed information on how you plan on
virtualizing USB.
Deepak
