As for "waking up" the iDrive knob, I've never tried what you're doing but I'll go out on a limb and say it doesn't need it. I'm willing to guess the knob is pretty dumb in that it just issues the same CAN commands over & over and lets the CAN gateway deal with the messages. Search my code in file idrivino.pde for the CAN section dealing w/ iDrive knob presses. You will be looking for CAN IDs starting with 0x1B8, which are the knob rotation & MENU button press. If you have an LCI iDrive controller, you'll have to sniff your own buttons related to the new direct buttons like NAV, etc.
