I am very much against USB consoles.  there can be a whole plethora of issues involved from OS-level to the device-level.  When I'm on the console, things have already gone bad.  I don't need to find out if the vendor has the right 'entitlement' established for me to download and load the driver or anything else..

It *needs* to work, I can't wait for the device on the other end to negotiate with the host system, etc.. 

I understand why people want it, but USB as it exists today isn't the way.  (I can screw down a rs232 connector and it can be secure, I can't attach USB with the same certainty).
