   Hi,

Markus asked it already, I'm asking again:

*Do we actually need the variable information?*

The point is that the information usually is available from context 
anyway, i.e. if you get the reply above from a command like 'usb_add 
host:0.12' you know it is host device 0.12 *without* parsing reply 
because you know you've asked for host device 0.12.

cheers,
   Gerd
