Raspberry pi ttyusb0 missing. I've a USB to Serial cable, using the . I also addressed a motor control board attached to the second USB port at /dev/ttyACM0. How can I resolve this? My Raspberry Pi is connected to a Arduino over USB. I've a USB to Serial cable, using the I'm trying to receive data from a IMU (EBIMU-9DOFv4) using a UART on my Raspberry Pi 5. You can even create /dev/ttyUSB0 with the command sudo mknod /dev/ttyUSB0 c 4 74, but it is created as virtual and is not related to the physical USB port. When I starte This ESP is connected to the Pi where I use Node-Red to read the values by reading the serial off /dev/ttyUSB0. Yesterday I reinstalled and did not find the CH340 Serial Bus 003 Device 001: ID 1d6b:0002 Linux What I have : Raspberry Pi 3 Model B Rev 1. I was able to make a testprint (by holding the button), but not via the raspberry If it's really Debian, and not Raspberry Pi OS, check that an update hasn't installed brltty or modem manager. ) Are I'm trying to open a Serial communication between a Raspberry Pi 3 (model B, running on Raspbian) and a device (a traffic counter to be precise). I addressed it at /dev/ttyUSB0 until today. This can make serial ports inaccessible (but not fully disappear). Since I'm already using RX/TX pins and my UART port for other purposes, I've tried to use USB When I plug in another device (eg Logitec Unifier Receiver), it is only detected via the native PI usb-ports, NOT via the extra front-USB-connecters from Deskpi Pro: I'm trying to open a Serial communication between a Raspberry Pi 3 (model B, running on Raspbian) and a device (a traffic counter to be precise). 2 What's it running : Linux piholeled 5. This setup had been working fine for the better part of a year and a week ago the Pi I had a RPi setup with 1 FTDI cable. I'm trying to receive data from a IMU (EBIMU-9DOFv4) using a UART on my Raspberry Pi 5. 52-v7+ #1570 SMP Mon Jul 4 13:29:14 BST 2022 armv7l GNU/Linux Occasionally, I encounter errors like: > **“/dev/ttyUSB0 not found over a time”** These errors sometimes disappear after a manual reboot, and other times the Raspberry Pi reboots itself Are you sure that /dev/ttyUSB0 is plugged in and available when you do the command? (Though you'd typically get " stty: /dev/ttyUSB0: No such file or directory " if that were the case. Since I'm already using RX/TX pins and my UART port for other purposes, I've tried to use USB ports, but it Unfortunately, it seems that "/dev/ttyUSB0" is missing (/not created), which causes an error. I was able to use /dev/ttyUSB0 in code without issues When I plugged in a second FTDI cable, with the same vendor and product ID, /dev/ttyUSB1 never Hi, it all worked in the past when the system was running on an earlier kernel. 15.
