yes, it works! from a cold start, the usb device comes to life with the 
"final" identity.

this is really the first step to make the "bare metal" running

now, linux is just missing the "real" dvb driver for this card!! ;-)

when i'll have some spare time i'll try to understand a bit the usb 
protocol with some usb snooping tool like this:

  http://benoit.papillault.free.fr/usbsnoop/
  http://www.toth.demon.co.uk/usb/reverse-0.2.txt

or  maybe try to dump usb log when the original driver is running on a 
vmware guest OS.

but may i ask, out of curiosity, if this "firmware loader" is just a 
hint of more meat to come?! ;-)
