As the image shows, I has an imu which is connected to orin by usb, and a ros node is used to open and read this /dev/ttyUSB to get imu data. But occasionally, the ros node can not read this /dev/ttyUSB correctly. The error dmesg output log when ros node failed to read is showed below. Can someone have a look at this issue. Thanks a lot.
