Glad to know it is solve.

Can you help by briefly explain how you decode these:

First, I assigned the device number and bus number

0x44000001

0x0000100F

0x00000018

0x00010100

and then done the configuration read type 1

0x05000001

0x0000100F

0x01080000

0x00000000

This may help others whose using CRA interface.
