Hello,

Thank you for your hint, and sry for the late response - had some finals  
for this term - todays my first day of hollidays, so i spent some time on  
the LR506 thing again.

I have played i bit with the patch. You had right, that  
m920x_identify_state wont work. But imho, if the usb-DevID=0x506, then it  
is in cold-state, so setting ".identify_state   = NULL" should to the work.

I set ".usb_ctrl = CYPRESS_FX2" to use the native functions provided in  
dvb-usb-firmware.c to download the firmware. Than i tryed to figure out  
the binary format of the .fw file. I guess I got it right.
I wrote a script which converts the snooped data into the propriated  
format. I gave it a try and to my surprise it worked :)

So, for short: Now I am able to download the fw to the cold device and  
lsusb tells afterwards, that the device has re-registered as the warm one  
(DevID=0x0500).

The firmware can be found at:  
http://danyserv.selfip.org/dir/LifeView/dvb-usb-tvwalker-lr506.fw

Now i have to figure out, how i can attach a frontend to it. No Idea how  
this will work - but ill play a bit with it.

Thx for the hint, again.

And if someone could give me some tipps I would be glad.
-Daniel
