Re: [Xen-devel] usb storage vitualization

[Deepak Manohar <mjdeepak@xxxxxxxxx>]

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
