udev rules (USB permissions)

In order to use OpenAuto with Linux-based OS (e.g. Raspbian) with udev, you must create a rule to allow communication with USB devices in R/W mode. Please see this issue in order to create secure udev rules for OpenAuto purposes.

The simplest rule looks like below one:

SUBSYSTEM=="usb", ATTR{idVendor}=="*", ATTR{idProduct}=="*", MODE="0660", GROUP="plugdev"

In order to add this rule to udev, do:

$ cd /etc/udev/rules.d

$ sudo touch openauto.rules

$ sudo nano openauto.rules

then paste above rule, save the file and reboot your device.

Please notice that above rule allows to open any USB device in R/W mode by any app installed on the system. Consider it as insecure.
