PS1, Line 191: usb_device_disable
Prefer two improvements:
1) move inside src/soc/intel/common/block/xhci.c
2) Check Current Connect Status(CCS) bit in the USB Port Status and Control register in the XHCI register block and then disable the unconnected devices. I believe it works for externally visible ports too.
