11/* protocol (from usblogging and the SDK:
12 *
13 * Always 7 bytes bulk message(s) for controlling
14 *
15 * First byte describes the command. Reads are 2 consecutive transfer (as always).
16 *
17 * General structure:
18 *
19 * write or first message of a read:
20 * <cmdbyte> VV <len> B0 B1 B2 B3
21 *
22 * second message of a read
23 * <cmdbyte> VV <len> R0 R1 R2 R3
24 *
25 * whereas 0 < len <= 4
26 *
27 * I2C address is stored somewhere inside the device.
28 *
29 * 0x01 read from EEPROM
30 *  VV = offset; B* = 0; R* = value(s)
31 *
32 * 0x02 read register of the COFDM
33 *  VV = register; B* = 0; R* = value(s)
34 *
35 * 0x05 write register of the COFDM
36 *  VV = register; B* = value(s);
37 *
38 * 0x06 write to the tuner (only for NXT6000)
39 *  VV = 0; B* = PLL data; len = 4;
40 *
41 * 0x03 read remote control
42 *  VV = 0; B* = 0; len = 4; R* = key
43 *
44 * 0x07 write to the remote (don't know why one should this, resetting ?)
45 *  VV = 0; B* = key; len = 4;
46 *
47 * 0x08 write remote type
48 *  VV = 0; B[0] = 0x01, len = 4
49 *
50 * 0x09 write device init
