But after I tried "sudo screen /dev/ttyACM0", it worked. I quit and tried the same command without "sudo", it also worked.</p> <p>I tried thsi way and that way many times. It seems "sudo" first will alway make things normal. But other operations like restart udev or even restart OS, or restart maple IDE, does NOT help.</p> <p>Why?</p> <p>Thanks! </p>
