Are those changes necessary to make it work for you? The + line was indeed needed to be able to tune. The - line is not necessary, it seemed like it wasn't necessary as two lines further the access to the tuner chip is enabled again (write 0x1a into 0x62). Maybe the location of that write is important. I'll see if I can find some other combinations that work for me. In the usb snoop, the write to 0x5a is actually a read from that register, which returns 0x0c. After that read there is a write of the same value. PS has anybody actually contacted the manufacturers of these chips to try to get a datasheet for the qt861 and zl10353?
