Hi, To configuring USB Access for phone, we have to use idVendor in a file /etc/udev/rules.d/51-android.rules like SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e12", MODE="0600", OWNER="<username>" For each phone there is a different idVendor. Is there a idVendor for udoo or should be done differently to have the access to the USB Udoo? Thanks for your response, Marie
