Did you install sick_tim from source or the the ROS package repository? Did you install the udev rules: https://github.com/uos/sick_tim/issues/77 What's the output of lsusb and of ls -l /dev/bus/*

Lip0 commented 5 years ago

yes,I install the udev rules, current user is a member of the plugdev group . the output of lsusb is the type of USB cable,the led of lidar is green. image image

The ls output is missing the subdirs, can you try ls -lR /dev/bus/usb instead?

Edit: I wanted to write ls -l /dev/bus/usb/* in the post above, that's why it was missing the relevant output :).

ls -lR /dev/bus/usb ![Uploading image.png…]() 选区_001

The lsusb output implies that you want to connect to the device through a third party USB to serial converter. This driver only supports direct connection to the USB plug of the device or Ethernet.

you mean the usb cable have problem? I need to change a usb cable?

jspricke commented 5 years ago

For USB you need to connect to the USB port of the laser scanner, which is behind the USB logo on the left on this picture: https://cdn.sick.com/media/ZOOM/5/25/025/IM0051025.png.

Closing because it's not a driver problem.
