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.
understood, I found with usb_serial convertor could lose some chatacter. but the usb-debug cable seem it keep all character.
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.
Is it in the git tree?
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...
the problem is some "modern" PC will left out serial port. then the cable could get cheap.
