Currently not supported. (Neither the demod-part nor the USB-part)

We have a driver for that, but it is maybe not optimized. (Can be found in

Not so sure. By sniffing USB on Windows and looking at the output.

Depend how incomplete. If it just specification of the performance - too
bad, if there is some programming information - good.

For DVB USB there is a small framework which was done to make integration
of new devices easier (it cares about data transfer and some API-specific
stuff which has to be done for each device). Normally a driver inside that
framework can concentrate on the real driver-dependent stuff - nothing

I use http://benoit.papillault.free.fr/usbsnoop/.

Yes. You should consider to work inside a checkout of v4l-dvb:

I don't know what you mean: you want to develop the firmware or just to
extract. If there is a firmware extracting is much easier. Normally
usbsnoop can be used for that.
