Hi Dave, I revisited the kernel log. It seems the debug host enumerated the debug target successfully. Can you please check the minicom configuration? The configure on my debug host looks like below. Welcome to minicom 2.7 OPTIONS: I18n Compiled on Jan 1 2014, 17:13:19. Port /dev/ttyUSB0, 01:28:02 Rate: 115200 Please make sure you have disabled runtime power management for USB devices and host controller in debug host. And sometimes, reboot the debug host helps when enumeration fails.
