I'm trying to find the relevant discussion. The link you gave in the 
previous mail:

  http://lkml.org/lkml/2009/4/21/408

does not offer any design analysis of vbus versus virtio, and why 
the only fix to virtio is vbus. It offers a comparison and a blanket 
statement that vbus is superior but no arguments.

(If you've already explained in a past thread then please give me an 
URL to that reply if possible, or forward me that prior reply. 
Thanks!)
