14 /* protocol (from usblogging and the SDK:
16 * Always 7 bytes bulk message(s) for controlling
18 * First byte describes the command. Reads are 2 consecutive transfer (as always).
22 * write or first message of a read:
23 * <cmdbyte> VV <len> B0 B1 B2 B3
25 * second message of a read
26 * <cmdbyte> VV <len> R0 R1 R2 R3
28 * whereas 0 < len <= 4
30 * I2C address is stored somewhere inside the device.
32 * 0x01 read from EEPROM
33 * VV = offset; B* = 0; R* = value(s)
35 * 0x02 read register of the COFDM
36 * VV = register; B* = 0; R* = value(s)
38 * 0x05 write register of the COFDM
39 * VV = register; B* = value(s);
41 * 0x06 write to the tuner (only for NXT6000)
42 * VV = 0; B* = PLL data; len = 4;
44 * 0x03 read remote control
45 * VV = 0; B* = 0; len = 4; R* = key
47 * 0x07 write to the remote (don't know why one should this, resetting ?)
48 * VV = 0; B* = key; len = 4;
50 * 0x08 write remote type
51 * VV = 0; B[0] = 0x01, len = 4
53 * 0x09 write device init
