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.
Thanks,
Baolu
