this causes some usb-ehci controllers to die while sending, so i did copy
that, but can be removed after successfull test

ok the 2nd was too few in the array 1 is enough

which ? i searched the whole v4l-dvb stuff , and did not find any controller
that used 2byte addresses , that makes ist hard to use other stuff for this,
but if you say ist already done , i would change it to the other

like i saw for stv0299 the set_symbolrate MUST be implementet bec. there is no
one in. also here the stuff with the 2 byte address
