16 *
17 * Always 7 bytes bulk message(s) for controlling
18 *
19 * First byte describes the command. Reads are 2 consecutive transfer (as always).
20 *
21 * General structure:
22 *
23 * write or first message of a read:
24 * <cmdbyte> VV <len> B0 B1 B2 B3
25 *
26 * second message of a read
27 * <cmdbyte> VV <len> R0 R1 R2 R3
28 *
29 * whereas 0 < len <= 4
30 *
31 * I2C address is stored somewhere inside the device.
32 *
33 * 0x01 read from EEPROM
34 *  VV = offset; B* = 0; R* = value(s)
35 *
36 * 0x02 read register of the COFDM
37 *  VV = register; B* = 0; R* = value(s)
38 *
39 * 0x05 write register of the COFDM
40 *  VV = register; B* = value(s);
41 *
42 * 0x06 write to the tuner (only for NXT6000)
43 *  VV = 0; B* = PLL data; len = 4;
44 *
45 * 0x03 read remote control
46 *  VV = 0; B* = 0; len = 4; R* = key
47 *
48 * 0x07 write to the remote (don't know why one should this, resetting ?)
49 *  VV = 0; B* = key; len = 4;
50 *
51 * 0x08 write remote type
52 *  VV = 0; B[0] = 0x01, len = 4
