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