I dislike this (usb_cdc_line_status() == 0x00). I think we need something more readable.
It should look like this instead: -- wait till USB device has been connected and serial port has been opened by the HOST While (usb_serial_port_open == FALSE) loop usb_serial_flush() -- poll USB at all times end loop Can we create an inline pseudo var?
