Hmm, you might want to change

No, this doesn't resolve the problem.
puts() I guess _should_ be a 'best effort'. Better, still, maybe we could add an environment variable which would switch puts() between flow-control and 'best effort', so that people have the choice.
/* Not tested */ unsigned int len = 0; while(len > 0) { usbtty_poll(); space = maxlen;
if(environment_variable_use_tty_flow_control) space = maxlen - usbtty_output.size;
if(space){ /* Do stuff */ } }
I think this is not useful since after the timeout has expired if I try to connect with usbtty the system boots immediately! O_o
