The ShuttleXpress is a hardware input device useful for controlling video and audio editing software. They can be configured for all sorts of uses though. A popular one seems to be media playback, but they could be a game controller, and so on.

It has seven kinds of input:

1. An infinitely spinning dial with clicky movement. Good for stepping through a clip frame-by-frame.
2. Another dial with limited movement that snaps back into place. Useful for fast-forwarding and re-winding.
3. Five mouse-like buttons.

To use in Linux and Kdenlive you will need to add a udev rule.

1. Plug-in the shuttle, use lsusb and note the ID info. ID 0b33:0020 in my case, but in the example on the Kdenlive]] documentation the product ID is 0030.
2. Create a file in /etc/udev/rules.d (for example 90-shuttlexpress.rules and add the line:
   

   SUBSYSTEMS=="usb", ATTRS{idVendor}=="0b33", ATTRS{idProduct}=="0020", MODE="0444"

   where 0b33 is the first part of the ID you noted, and 0020 is the second.

3. Restart the udev stuff with # udevadm control --reload and # udevadm trigger.
4. Open Kdenlive, go: Settings > Configure Kdenlive… > JogShuttle, and once you enable and select your device you should be able to configure the buttons as you wish.

• NB: the FF/RW wheel seems bugged in this setup… it seems to work like a mouse scrollwheel, but reversed
