Hi Sergei,
Yes, I didn't mix them up. Our product supports 3 modes: PCIE only, USB only, and PCIE+USB.
Normally, it would be PCIE mode. When we want to reproduce some crash issue, we will switch it from PCIE mode to PCIE+USB mode.
In this scenario, the USB port is used for capturing memory dump as our tool is designed based on Qualcomm USB Sahara protocol.
Thanks.
