seems like the problem is based on the udev rules

working udev rule:
SUBSYSTEM=="usb", ATTRS{idVendor}=="0b33", ATTRS{idProduct}=="0030", MODE="660", GROUP="audio"
SUBSYSTEM=="usb", ATTRS{idVendor}=="0b33", ATTRS{idProduct}=="0020", MODE="660", GROUP="audio"
SUBSYSTEM=="usb", ATTRS{idVendor}=="0b33", ATTRS{idProduct}=="0010", MODE="660", GROUP="audio"

however, if you are using the contour with kdenlive, you need:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0b33", ATTRS{idProduct}=="0020", MODE="0444"
which doesn't work with ardour

so you have to choose to use the shuttle device in kdenlive or ardour

my solution to use it for both programs - set udev rule to:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0b33", ATTRS{idProduct}=="0020", MODE="0664" OWNER="MYUSER"

I'm not shure exactly why this is the only version that works.. maybe someone who understands udev better than me could clarify that.
