/*

|
Although we had envisioned BMI to run on top of HTC, this is not what the
|
||
|
|
final implementation boiled down to on dragon. Its a part of BSP and does
|
||
|
|
not use the HTC protocol either. On the host side, however, we were still
|
||
|
|
living with the original idea. I think the time has come to accept the truth
|
||
|
|
and separate it from HTC which has been carrying BMI's burden all this while.
|
||
|
|
It shall make HTC state machine relatively simpler
