USB2.0 BULK stream .buffersize is currently 512 and your patch increases
it to the 65424. I don't know how this value should be determined. I
have set it as small as it is working and usually it is 512 used almost
every driver. 511 will not work (if not USB1.1 configured to the endpoints).

Could someone point out how correct BULK buffersize should be
determined? I have thought that many many times...

Also one other question; if demod is powered off and some IOCTL is
coming - like FE_GET_FRONTEND - how that should be handled? v4l-dvb
-framework does not look whether or not demod is sleeping and forwards
that query to the demod which cannot answer it.

Antti
