Thanks, that worked fine infact
$ ls -l /dev/dvb/adapter0/
now correctly report 212 instead of 250 as it used to be... :)
I still have some issues though.
If I run szap I'm not able to lock to a channel. At least not always....
Sometimes I get this output:

$ sudo szap OpenSky
reading channels from file '/home/esa/.szap/channels.conf'
zapping to 551 'OpenSky':
sat 2, frequency = 11262 MHz H, symbolrate 27500000, vpid = 0x0000, apid 
= 0x0000
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

status 00 | signal 3a97 | snr 9215 | ber 00000000 | unc 00000000 |

while other times I'm able to lock...

Any idea or explanation of this output?
