  11  *
  12  * Always 7 bytes bulk message(s) for controlling
  13  *
  14  * First byte describes the command. Reads are 2 consecutive transfer (as always).
  15  *
  16  * General structure:
  17  *
  18  * write or first message of a read:
  19  * <cmdbyte> VV <len> B0 B1 B2 B3
  20  *
  21  * second message of a read
  22  * <cmdbyte> VV <len> R0 R1 R2 R3
  23  *
  24  * whereas 0 < len <= 4
  25  *
  26  * I2C address is stored somewhere inside the device.
  27  *
  28  * 0x01 read from EEPROM
  29  *  VV = offset; B* = 0; R* = value(s)
  30  *
  31  * 0x02 read register of the COFDM
  32  *  VV = register; B* = 0; R* = value(s)
  33  *
  34  * 0x05 write register of the COFDM
  35  *  VV = register; B* = value(s);
  36  *
  37  * 0x06 write to the tuner (only for NXT6000)
  38  *  VV = 0; B* = PLL data; len = 4;
  39  *
  40  * 0x03 read remote control
  41  *  VV = 0; B* = 0; len = 4; R* = key
  42  *
  43  * 0x07 write to the remote (don't know why one should this, resetting ?)
  44  *  VV = 0; B* = key; len = 4;
  45  *
  46  * 0x08 write remote type
