I had a lot of problems in the beginning - but I starts read all I find, and now its working well.
First - go to Devices, and see that you have a device, Shipdriver. Rightclick on this and choose Game controller settings, and Properties. You will come to the Test page, and can check how the settings are.
If any wrong, go to Settings tab, and Calibrate, Follow the instructions, and all shall be done.
First I had tried another way to calibrate it, with use of the http://www.piengineering.com/developer/splatsdk.php (http://www.piengineering.com/developer/splatsdk.php)
SDK kit. But, this must be used with very care. It gives control to a lot of functions on Shipdriver, and its possible to reset it. You also find a lot of information in http://shipdriver.com/support/ (http://shipdriver.com/support/)
Use the Device settings - normally it will works fine. Remember put in mode 1 before starts calibraiting, and use the stick - not the steeringwheel when you calibrate.
