Ugh, no, never use the usb-serial driver as a console device.
That was a bad hack done as a bet many years ago. For many obvious reasons it does not work well.
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'?
The usb-serial console code should handle this, I thought we fixed it a while ago.
But this kind of interface is not what these devices are good for. They are for the debug port information, not as a usb-serial console device. Otherwise they are way too expensive of a device...
