   1 /* DVB USB compliant linux driver for Technotrend DVB USB boxes and clones
   2  * (e.g. Pinnacle 400e DVB-S USB2.0).
   3  *
   4  * The Pinnacle 400e uses the same protocol as the Technotrend USB1.1 boxes.
   5  *
   6  * TDA8263 + TDA10086
   7  *
   8  * I2C addresses:
   9  * 0x08 - LNBP21PD   - LNB power supply
  10  * 0x0e - TDA10086   - Demodulator
  11  * 0x50 - FX2 eeprom
  12  * 0x60 - TDA8263    - Tuner
  13  * 0x78 ???
