Voila.
This is the access with makes the dvb-pll-driver not create the tuner
driver.
This is (I forgot the correct name) read-without-write-i2caccess. It is
bad handled by the dibusb-driver and it can destroy the eeprom on the USB
side.
Please try whether the attached patch fixes the whole situation for you.
If so, please send back a line like this:
