With Greg's USB Debug, host and target can talk.
target with console=ttyUSB0,115200n8
host with cat /dev/ttyUSB0
But if use minicom in host, it will not show '\r', I guess the usb debug
cable eat return char. Greg, Can you add that back in usb_debug by
replacing '\n' with '\r', '\n'?
With Eric code in LinuxBIOS, it will report "No device found in debug
port"
