xv-11-lidar cannot find the right port
I am using ubuntu mate 20.04 focal and i have installed ros noetic, i'm following the following tutorial http://wiki.ros.org/xv_11_laser_drive...
when i try to run the following command
rosrun xv_11_laser_driver neato_laser_publisher port_:=/dev/ttyACM0
I get the following error: [ERROR] [1582038870.703246684]: Error instantiating laser object. Are you sure you have the correct port and baud rate? Error was open: No such file or directory
in the tutorial when i try to run the following command it says "error file doesn't exist"
echo 'SUBSYSTEMS=="usb", KERNEL=="ttyUSB[0-9]*", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", SYMLINK+="sensors/ftdi_%s{serial}"' > /etc/udev/rules.d/52-ftdi.rules
when i change 52-ftdi.rules to the actual file that is in the rules.d folder which is 70-snap.snapd.rules it says "permission denied"
when i run dmesg -w i get the following output usb 1-1.2: Product: USB Serial usb 1-1.2: Manufacturer: Teensyduino usb cdc_acm 1-1.2:1.0 ttyACM0: USB ACM device
when i run lsusb i get the following Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 046d:c077 Logitech, Inc. M105 Optical Mouse Bus 001 Device 003: ID 1a2c:2124 China Resource Semico Co., Ltd Bus 001 Device 008: ID 16c0:0483 Van Ooijen Technische Informatica Teensyduino Serial Bus 001 Device 007: ID 046d:0892 Logitech, Inc. OrbiCam Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
i'm not sure if the problem is because the rosrun instruction isn't getting the right port? if this is the problem then how do i change the permissions in the 70-snap.snapd.rules file? or if the problem is due to something else?
the lidar does turn when i plug it in and as far as i can tell it's not a hardware issue.....
please help me
