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 
hg/pb/v4l-dvb.stk3000p)

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 
else.

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

Yes. You should consider to work inside a checkout of v4l-dvb: 
http://www.linuxtv.org/repo/

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.

best regards,
Patrick.
