If the hardware is implemented correctly, and you properly initialize the 'D12, then connect the cable, you should expect to see something similar to the following sequence of events...

Не знаю с чем вы работаете. Но в PDI нужно после получения адреса(SetAdress, если устройство одно, то адрес обычно равен 2) нужно этот
адрес передать в драйвер шины(PDI) и разрешить его(Set Adress/ Enable для PDI).

Судя по тому что получаете запрос Get Config Descriptor, Set Adress в
контроллере обрабатывается не корректно.
