Hi, Aapo, It's nice to hear from you ;-)

I though the problem was what you said on your last point: cat
/dev/dvb/adapter0/dvr0 gives no byte, so usbsnoop and such are useless
tools at this point. Anyway I've tried them, but they gave me no
results.
On the other side, I'm embarrassed because I never thought of
running "lsusb -v" again, after the firmware was uploaded :-$. Thanks
for the tip! Below you'll find the result of that command. Correct me
if I'm wrong, but the problem might be I'm configuring the device for
bulk transfers, when it wants to do isochronous ones (also, what about
*MaxPacketSize* values?). Il try to play a little with that and post
the results...
