STUSB1602 2 port source at the same time

[Yavuzhan_]

Hello,

I am trying to negotiate set the 2 ports as a source at the same time using the firmware package "STSW_STUSB012_v1_1". When I work only 1 port it is succesfull to be source which has the profiles (5V-3A, 9V-3A, 15V-3A, 20V-5A) and it negotiates for other sink devices. But When I work with 2 ports as a source there is no negotiate any profiles with any device. Can anyone help me on this?

Thank you.
