Did you try my suggestion I sent the past December 26th? Quote: El Fri, 26 Dec 2008 11:08:33 -0200 Mauro Carvalho Chehab escribió: > > Luca, > > > > Could you please verify this issue? No, I don't have 2.6.28, but I guess that maybe once usb_register is called the dvb-usb subsystem asynchronously (is that an smp system?) starts polling the remote before the rc_decode function pointer has been initialized. Could you try to initialize it to NULL before calling usb_register? Bye -- Luca
