Hi Bjørn,
Thank you for your good advice. Actually it's my typo for 'QDL'. It should be 'Diag' port.
Please see my local setting for PCIE+USB mode:

jbd@jbd-ThinkPad-P1-Gen-4:~/git/net-next$ lsusb | grep 05c6
Bus 003 Device 003: ID 05c6:901d Qualcomm, Inc. Qualcomm HS-USB Android Diag 901D
jbd@jbd-ThinkPad-P1-Gen-4:~$ lspci | grep Foxconn
0000:08:00.0 Wireless controller [0d40]: Foxconn International, Inc. Device e0ab

One more, should I add a new layout for Qualcomm SDX55 platform? As there are G1K,G2K, SIERRA and HUAWEI layout, none of them includes Qualcomm SDX55.

Thanks
