Are you still hacking that device?
I tried to order Intel CE6230 device but got EC168 (SinoVideo 3420A-2).
I take one USB-sniff and here are commands as I think:
00 firmware download
01 ? config
03 demodulator
04 ? GPIO (LED)
10 streaming control
20 I2C read
21 I2C write
30 HID table download
Looks like EC168 has EC100 demodulator integrated. And programming this
demodulator seems to be rather easy, not very many bytes...
