When I do:

$ tzap -r Telecinco
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 850000000 Hz

dvb-usb writes in syslog:
Oct 10 20:47:07 localhost kernel: dvb-usb: could not submit URB no. 0 -
get them all back

Channel is locked but nothing comes out from dvr0

Scanning does not work also getting always:
$ ./scan dvb-t/es-Madrid

I have a Freecom DVB-T USB stick, tried with stock (debian etch) and
latest mercurial sources for dvb-utils and modules on linux 2.6.18 and
2.6.19-rc1 (exactly the same happens).

The device works fine in another computer with a quite old kernel and
drivers (I think 2.6.15.something with drivers built from cvs sources).

Any clue? Thanks in advance for your help.

Oscar.
