Hi Andrea,

About one year ago I started to work on it, but gave up because I haven't 
had any information about demodulator and tuner. This completely changed 
now, because, as you correctly stated, every single piece of the 
"Frontend" is now supported.

I have some information about the FX2 for this device, but it is 1 year 
old and has maybe changed. 

I extracted the firmware using the windows driver and usbsnoop. I called 
the file "dvb-usb-pctv-400e-01.fw", but didn't make it public.

I started to implement the firmware interface in the driver, by knowing 
that the interface is almost similar to the ttusb-interface. I think I 
still have the corresponding dvb-usb-code at home - I'll take a look.

However I also heard, that there are some problems with the device, 
hardware or software (Windows). Maybe in the meantime there is a new 
Windows-driver from Pinnacle, which is changing the whole 
firmware-interface (instead of isochronous maybe bulk is used, maybe 
also some requests).

To figure that out, one needs to do more usbsnooping.

Hope that helps,
Patrick.
