Foxconn SDX55 T77W175 device is working in PCIe mode normally. You can find the PCIe support in drivers/bus/mhi/pci_geneirc.c file. But in some scenario, we need to capture the memory dump once it crashed. So a diag port under USB driver is needed. Only interface 0 is used: jbd@jbd-ThinkPad-P1-Gen-4:~$ lsusb | grep 05c6 Bus 003 Device 010: ID 05c6:901d Qualcomm, Inc.
