Revision history [back]

I finally find out how to access to usb without typing sudo. First of all, I create a new file in /etc/udev/rules.d named 10-mydevice.rules and added this line inside:

ATTRS{idProduct}=="[VENDOR_ID]", ATTRS{idVendor}=="[PRODUCT ID]", MODE="666", GROUP="plugdev"

where VENDOR_ID and PRODUCT_ID are specified by

lsusb -v

Then I simply checked if my user was part of plugdev group by typing

groups USERNAME

Finally I saved and closed my file and entered the following in the terminal window for refreshing the rules:

sudo udevadm trigger

Right now I can run my node by using rosrun without root privileges or run the node from inside QtCreator!!! Hope this could help other people!
