Did you use the correct config?
http://snapshots.linaro.org/96boards/dragonboard820c/linaro/debian/latest/config-5.4.0-qcomlt-arm64

#3

yes i had use the same defconfig , in general will use the defconfig and distro.config to create a .config, which is similar to config-5.4.0-qcomlt-arm64

make CROSS_COMPILE=$TC64 ARCH=arm64 -j32 defconfig distro.config

usb are working for you?
