Hi to everyone,
I was able to make working my LITE-ON USB2.0 DVB-T (maybe is possible also to make works all clones of this dvb-t pen) on kernel 2.6.19 as it works on 2.6.20.
It was possible just "hacking" a file and exactly dvb-usb-dvb.c (in dvb-usb) and inserting before line /* re-assign sleep and wakeup functions */ (exactly at line 177) an msleep(1000);.
With this is msleep is possible to make LITE-ON USB2.0 DVB-T work also under 2.6.19 kernel, without reading always no frontend...

Now a question to everyone...
Was someone able to make work Nova-t-stick?? I'm going mad!
