Bosch KTS 520 - No communication via USB or Serial

1
Hi guys,
I have a Bosch KTS 520 for daily use and a few days ago I lost communication via USB or Serial.
There is no USB detection whatsoever, I checked and switched cables, nothing.
I then tried the old serial COM and no communication on that port either, Bosch DDC can't detect or test the interface.
I tried both via car's OBD port for power and external power supply, the green LED flashes like it should and at power up I can hear the relays activating but there is no communication on either ports.
I went to a GSM store and replaced the PDIUSB IC near the USB connector, wich handles communication but nothing, nothing at all. If the USB is bad I guess at least the COM would work but it doesn't.
Do you guys know anything about this ?

Check the USB port. I had to change it on my one and it helped. I heard it's common fault in them

But if serial connection doesn't work, i think there is a different problem.
