820-01949 after replacing CD32 no usb-c communication

[meineiid]

Hi I got a MacBook A2251 2020 with only 5volt on usb-c. Replaced both CD32 on the right side and got 20 volts back on all ports and Macbook starts normally. But USB devices don't work no usb3 or thunderbolt ist working. My external SSD gets Power but no blinking...
Any ideas?

Each 3217 has an installation order according to the diagram. 1/2/3/4 on boards with four ports and 1/2 with two-port. In no case should they be swapped, incorrect operation is possible! But in no case should you install 3217 with two ports on a four-port board and vice versa. This will not work. Before removing, number the CD.
