    Sorry, it is my fault.
    I trace into the function and lead to my save_state() low level function that
    call the read data function to store the state. :)

    There also another bug on the low level frob_control function. I am not clear
    about its operation at first, so I change the control like (old & ~mask) |
    value, but acutally it is
    (old | mask) & ~val, set all vaule in mask to 1 and those in val to zero. I
    read the usage of it in the code and realise what I done was wrong.

    I am getting close to a working code, and now I have the device pass the
    IEEE1284 complient test, but fail at deviceid, saying 0x4 mode is rejected by
    device. :) I think is propley my fault somewhere.

    Thanks for your help!
